Recent Soviet Conferences on Psychology and Psychophysiology: Topical Summaries

The following conferences, held in 1964 and 1965, were reported in the journals Voprosy psikhologii (V), Zhurnal vysshey nervnoy deyatel'nosti im. I. P. Pavlova (P), and Fiziologicheskiy zhurnal SSSR im. I. M. Sechenova (F).     

Editor's Note

This issue of Soviet Psychology — Vol. V, No. 1 — marks a new point in the development of English translations of Soviet psychology and psychiatry. Our original journal, published in Volumes I-IV as Soviet Psychology and Psychiatry, has given birth to two new journals: Soviet Psychology and Soviet Psychiatry. This will give International Arts and Sciences Press the opportunity to publish twice as much material from the fund of Soviet theory and research in the study of human behavior. The increased space in this new journal will allow for a broader coverage of Soviet work in psychology, as outlined in our last issue, the special Handbook of Soviet Psychology.     

Administrative Reform: Psychology Faculties

At the end of 1965 an event occurred that will significantly affect the development of Soviet psychology: on December 6, 1965, V. N. Stoletov, Minister for Higher and Specialized Secondary Education of the RSFSR, issued a decree changing the Psychology Departments [otdeleniy] of Moscow and Leningrad Universities into separate Schools [fakul'tety] of Psychology, and establishing their structure. Students will be admitted to the Schools of Psychology beginning September 1, 1966.     

Noted Figures in the History of Soviet Psychology: Pictures and Brief Biographies

Presented below are Soviet evaluations of the careers and contributions of noted figures in the history of Soviet psychology. The passages are drawn from the Pedagogical Dictionary [Pedagogicheskiy slovar'; Moscow: Acad. Pedag. Sci. RSFSR, 1960] and Pedagogical Encyclopedia [Pedagogicheskaya entziklopediya; Moscow: Acad. Pedag. Sci., 1964-1965], unless otherwise indicated.     

Editor's Preface

The occasion of the XVIIIth International Congress of Psychology in Moscow this summer is an event of importance for Soviet psychology and for world psychology. Accordingly, we have prepared this special issue of Soviet Psychology and Psychiatry to serve as a guide to Soviet psychology. I hope that this guide will be especially useful to Western psychologists participating in the Moscow Congress, and that it will be useful to a broader public as well.     

Current Soviet Psychology: A Systematic Review

Scope and Nature of the Present Report: This presentation is based on materials, primarily books, that have become available since the completion of the chapter on "Recent Developments in Soviet Psychology," published in Vol. 15 of the Annual Review of Psychology (Brozek, 1964, pp. 493-594). It is closer to a commentary on Soviet contributions that are of potential interest to American psychologists (a "bibliography with comment") than to a critical appraisal. The latter is the task of topical reviews and monographic presentations.     

The Theory of Set in the Light of Reflex Theory

It is well known to all those acquainted with D. N. Uznadze's theory of set [ustanovka] (1) that this theory was meant to answer the question of "the character and inner structure of human activity" [11; 79]. But, as A. T. Bochorishvili correctly noted, we do not yet have "clarity in basic concepts. … Soviet psychology cannot yet go so far as to speak of the content of the basic concept of the psychology of set, of the content of set itself" [5: 15]. As a panacea for overcoming these differences of opinion, Bochorishvili proposes that we "widely and actively develop investigations of the theoretical bases of the psychology of set as D. N. Uznadze understood if" (ibid.).     

A Contribution to the Comparative Epidemiology of Schizophrenia in Urban and Rural Places

In psychiatry, epidemiology rests upon statistical studies of mental illness in the population. Much attention was given to this as early as the work of Esquirol, (1) and I. F. Riul' (2) in our country. Zemstvo psychiatrists contributed much in the field of psychiatric morbidity. (3-8) However, as a result of the lack of outpatient psychoneurological institutions in prerevolutionary Russia, these studies, like the majority of those currently being conducted by psychiatrists abroad, resolved fundamentally to isolated unidimensional selective surveys of particular groups in the population. The existence in the Soviet Union of a broad network of outpatient psychiatric institutions permits Soviet psychiatrists to go beyond single-factor selective surveys, to make a systematic study of mental illness in accordance with the data of current dispensary records, and to provide timely therapeutic and social prophylactic assistance to the ill, i.e., to conduct epidemiological research on a higher level of scientific methodology. A number of such studies has been published. (8-23) Therefore the statement by Lin and Standley, (24) who allege — in a monograph, The Role of Epidemiology in Psychiatry, published by the World Health Organization — the absence of epidemiological psychiatric studies in the Soviet Union, must be rejected as unfounded.     

Synthesis of Certain 5′-Substituted Derivatives of Ribavirin and Tiazofurin

Abstract

The synthesis of several 5′-substituted derivatives of ribavirin (1) and tiazofurin (3) are described. Direct acylation of 1 with the appropriate acyl chloride in pyridine-DMF gave the corresponding 5′-O-acyl derivatives (4a-h). Tosylation of the 2′, 3′-O-isopropylidene-ribavirin (6) and tiazofurin (11) with p-toluenesulfonyl chloride gave the respective 5′-O-p-tolylsulfonyl derivatives (7a and 12a), which were converted to 5′-azido-5′-deoxy derivatives (7b and 12b) by reacting with sodium/lithium azide. Deisopropylidenation of 7b and 12b, followed by catalytic hydrogenation afforded 1-(5-amino-5-deoxy-β-D)-ribofuranosyl)-1, 2, 4-triazole-3-carboxamide (10b) and 2 - (5 -amino- 5-deoxy- β-D-ribofuranosyl) thiazole-4-carboxamide (16), respectively. Treatment of 6 with phthalimide in the presence of triphenylphosphine and diethyl azodicarboxylate furnished the corresponding 5′-deoxy-5′-phthaloylamino derivative (9). Reaction of 9 with n-butylamine and subsequent deisopropylidenation provided yet another route to 10b. Selective 5′-thioacetylation of 6 and 11 with thiolacetic acid, followed by saponification and deisopropylidenation afforded 5′-deoxy-5′-thio derivatives of 1-β-D-ribofuranosyl-1, 2, 4-triazole-3-carboxamide (8a) and 2-β-D-ribofuranosylthiazole-4-carboxamide (15), respectively.     

On the Content of Social Psychology

1. Attitude to the Discussion: A discussion of social psychology was opened in the pages of Voprosy psikhologii. [Translated in this journal, 1963, 1 (3), 32-38. — Ed.] This event has both a good and bad side. The good side is that, finally, the central organ of Soviet psychology has begun to speak about social psychology. Soviet psychologists will at last state their positive word about social psychology. The discussion will permit a more profound definition of the content of social psychology and will attract the attention of the Soviet public to the phenomena of social psychology. The bad side is that while much is said about the content of social psychology, the most urgent problems for Soviet social psychology is not so much one of its content as of the development of concrete methods and concrete investigations. A. V. Baranov's article [5] presents an incorrect understanding of the history and contemporary state of social psychology in the USSR.     

Synthetic Nucleosides and Nucleotides. XX1. Synthesis of Various 1-β-D-Xylofuranosyl-5-Alkyluracils and Related Nucleosides

Abstract

Treatment of D-xylose (1) with 0.5% methanolic hydrogen chloride under controlled conditions followed by benzoylation and acetolysis afforded crystalline 1-O-acetyl-2, 3, 5-tri-O-benzoyl-α-D-xylofuranose (4) in good yield. Coupling of 4 with 2, 4-bis-trimethylsilyl derivatives of 5-alkyluracils (methyl, ethyl, propyl and butyl) (5a-5d), 5-fluorouracil (5e) and uracil (5f) in acetonitrile in the presence of stannic chloride gave 1-(2,3,5-tri-O-benzoyl-β-D-xylofuranosyl)-nucleosides (6a-6f). Saponification of 6 with sodium methoxide afforded 1-β-D-xylofuranosyl-5-substituted uracils (7a-7f). Condensation of 4 with free adenine in similar fashion and deblocking gave carcinostatic 9-β-D-xylofuranosyladenine (7g).     

Studies on the Dehydration of New 2- (Pentitol-1-YL) Pyridines Having D-Gulo,D-IDO,and L-Manno Configurations

Abstract

Fusion of 2-trimethylsilylpyridine and tetra-O-acetyl-aldehydo-D-xylose or 2,3:4,5-di-O-isopropylidene-aldehydo-L-arabinose led, after removing of the protecting groups, to 2-(pentitol-1-yl)pyridines of D-gulo and D-ido or L-manno configurations. Dehydration of the sugar-chain with D-gulo and D-ido configurations gave the corresponding 2′,5′-anhydro derivatives, whereas 2-(5-O-isopropyl-L-manno-pentitol-1-yl)-pyridine was the only compound formed by dehydration of the sugar-chain with L-manno configuration. Structural proofs are based on ¹H and ¹³C NMR spectra.     

Synthesis of Certain 4-Substituted-1-β-D-Ribofuranosyl-3-Hydroxypyrazoles Structurally Related to the Antibiotic Pyrazofurin

Abstract

Several 4-substituted-1-β-D-ribofuranosyl-3-hydroxypyrazoles were prepared as structural analogs of pyrazofurin. Glycosylation of the TMS derivative of ethyl 3(5)-hydroxypyrazole-4-carboxylate (3) with 1-0-acetyl-2,3,5-tri-0-benzoyl-D-ribofuranose in the presence of TMS-triflate gave predominantly ethyl 3-hydroxy-1-(2,3,5-tri-0-benzoyl-β-D-ribofuranosyl)pyrazole-4-carboxylate (4a), which on subsequent ammonolysis furnished 3-hydroxy-1-β-D-ribofuranosylpyrazole-4-carboxamide (5). Benzylation of 4a with benzyl bromide and further ammonolysis gave 3-benzyloxy-1-β-D-ribofuranosylpyrazole-4-carboxamide (8a). Catalytic (Pd/C) hydrogenation of 8a afforded yet another high yield route to 5. Saponification of the ester function of ethyl 3-benzyloxy-1-β-D-ribofuranosylpyrazole-4-carboxylate (7b) gave the corresponding 4-carboxylic acid (6a). Phosphorylation of 8a and subsequent debenzylation of the intermediate 11a gave 3-hydroxy-1-β-D-ribofuranosylpyrazole-4-carboxamide 5′-phosphate (11b). Dehydration of 3-benzyloxy-1-(2,3,5-tri-0-acetyl-β-D-ribofuranosyl)pyrazole-4-carboxamide (8b) with POCl₃ provided the corresponding 4-carbonitrile derivative (10a), which on debenzylation with Cl₃SiI gave 3-hydroxy-1-(2,3,5-tri-0-acetyl-β-D-ribofuranosyl)pyrazole-4-carbonitrile (13). Reaction of 13 with H₂S/pyridine and subsequent deacetylation gave 3-hydroxy-1-β-D-ribofuranosylpyrazole-4-thiocarboxamide (12b). Similarly, treatment of 13 with NH₂OH afforded 3-hydroxy-1-β-D-ribofuranosylpyrazole-4-carboxamidoxime (14a), which on catalytic (Pd/C) hydrogenation gave the corresponding 4-carboxamidine derivative (14b). The structural assignment of these pyrazole ribonucleosides was made by single-crystal X-ray analysis of 6a. None of these compounds exhibited any significant antitumor or antiviral activity in cell culture.     

Synthesis of Pyrazolo[3, 4-d]Pyrimidine Ribonucleoside 3′, 5′-Cyclic Phosphates Related to cAMP,cIMP and cGMP1

Abstract

The synthesis of pyrazolo[3,4-d]pyrimidine ribonucleoside 3′, 5′-cyclic phosphates related to cAMP, cIMP and cGMP has been achieved for the first time. Phosphorylation of 4-amino-6-methylthio-1-β-D-ribo-furanosylpyrazolo[3,4-d]pyrimidine (1) with POCl₃ in trimethyl phosphate gave the corresponding 5′-phosphate (2a). DCC mediated intramolecular cyclization of 2a gave the corresponding 3′, 5′-cyclic phosphate (3a), which on subsequent dethiation provided the cAMP analog 4-amino-1-β-D-ribofuranosylpyrazolo[3, 4-d]pyrimidine 3′, 5′-cyclic phosphate (3b). A similar phosphorylation of 6-methylthio-1-β-D-ribofuranosylpyrazolo[3, 4-d]pyrimidin-4(5H)-one (5), followed by cyclization with DCC gave the 3′, 5′-cyclic phosphate of 5 (9a). Dethiation of 9a with Raney nickel gave the cIMP analog 1-β-D-ribofuranosylpyrazolo[3, 4-d]pyrimidin-4(5H)-one 3′, 5′-cyclic phosphate (9b). Oxidation of 9a with m-chloroperoxy benzoic acid, followed by ammonolysis provided the cGMP analog 6-amino-1-β-D-ribofuranosylpyrazolo [3, 4-d] pyrimidin-4(5H)-one 3′, 5′-cyclic phosphate (7). The structural assignment of these cyclic nucleotides was made by UV and H NMR spectroscopic studies.     

Synthesis of Some Novel Acyclolumazine N-1 Nucleosides

Abstract

Reactjon of (2-acetoxyethoxy)methyl bromide with the silylated lumazine bases (1-6) in the presence of n-Bu₄NI leads to the formation of the nucleosides 8, 10, 12, 14, 16 and 18 respectively. Deacetylation with methanolic ammonia afforded the free nucleosides 9, 11, 13, 15, 17 and 19, respectively, in good yields. Structural proofs of the newly synthesized compounds are based on elemental analyses, UV and ¹H-NMR spactra. None of the acyclic nucleosides exhibited antiviral activity against HSV-1 in vitro.     

Nucleosides. 131. The Synthesis of 5-(2-Chloro-2-Deoxy-β-D-arabino-Furanosyl)Uracil. Reinterpretation of Reaction of ψ-Uridine With α-Acetoxyisobutyryl Chloride. Studies Directed Toward the Synthesis of 2′-Deoxy-2′-Substituted Arabino-Nucleosides. 2

Abstract

Treatment of ψ-uridine (3) with α-acetoxyisobutyryl chloride in acetonitrile gave, after deprotection, a mixture of four products: 5-(2-chloro-2-deoxy-β-D-arabinofuranosyl)uracil (10a), its 3′-chloro xylo isomer (11a), 2′-chloro-2′-deoxy-ψ-uridine (9a) and 4,2′-anhydro-ψ-uridine (8a). Each component was isolated by column chromatography. Compound 9 was converted to the known 1,3-dimethyl derivative 2 by treatment with DMF-dimethylacetal. Treatment of 10 and 11 with NaOMe/MeOH afforded the same 4,2′-anhydro-C-nucleoside 8. The 1,3-dimethyl analogues of 10 and 11, however, were converted to 2′,3′-anhydro-1,3-dimethyl-ψ-uridine (13) upon base treatment. The epoxide 13 was also prepared in good yield by treatment of 10 and 11 with DMF-dimethylacetal.     

Synthesis and X-Ray Crystal Structure of 3-Amino-1-β-D-Ribofuranosyl-s-Triazolo[5, 1-c]-s-Triazole

Abstract

The first chemical synthesis of 3-amino-1-β-D-ribofuranosyl-s-triazolo[5,1-c]-s-triazole (6) is described. Direct glycosylation of 3-amino-5(7)H-s-triazolo[5,1-c]-s-triazole (2) with 1-O-acetyl-2,3,5-tri-O-benzoyl-D-ribofuranose (3) in the presence of TMS-triflate gave 3-amino-1-(2,3,5-tri-O-benzoyl-β-D-ribofuranosyl)-s-triazolo[5, 1-c]-s-triazole (4) which, on ammonolysis, gave 6. The absolute structure of 6 is determined by X-ray diffraction techniques employing Mo Kα radiation. The structure is solved by direct methods and refined to the R value of 0.044 by using a full-matrix least-squares method. The sugar of 6 has a ³T₂ configuration. The torsion angles about the C5′–C4′ bond are both gauche and the torsion angle about the glycosidic bond is in the anti range. Each azole ring of the aglycon is planar and the dihedral angle between the planes of the rings is 3.6°.     

Synthesis and Antiviral Activity of 5′-O-Sulfamoyluridine Derivatives

Abstract

A series of 5′-O-[[[[(alkyl)oxy]carbonyl] amino] sulfonyl] uridines have been synthesized by reaction of cyclohexanol, palmityl alcohol, 1,2-di-O-benzoylpropanetriol and 2,3,4,6-tetra-O-benzoyl-L-glucopyranose with chlorosulfonyl isocyanate and 2,3′-O-isopropylidene-uridine. Another series of 5′-O-(N-ethyl and N-isopropylsulfamoyl) uridines have been prepared by reaction of 2′,3′-O-isopropylidene and 2′,3′-di-O-acetyluridine with N-ethylsulfamoyl and N-isopropylsulfamoyl chlorides. All compounds were tested against HSV-2, VV, SV and ASFV viruses. 2′,3′-Di-O-acetyl-5′-O-(N-ethyl and N-isopropylsulfamoyl) uridine showed significant activities against HSV-2. 5′-O-[[[[(2,3,4,6-Tetra-O-benzoyl-β-L-glucopyranosyl)oxy]carbonyl]amino] sulfonyl]-2′,3′-O-isopropylideneuridine was very active against ASFV.     

Synthesis of Brunfelsamidine Ribonucleoside and Certain Related Compounds by the Stereospecific Sodium Salt Glycosylation Procedure

Abstract

A synthesis of 2,4-dideazaribavirin ( 2 ), brunfelsamidine ribonucleoside ( 8c ) and certain related derivatives are described for the first time using the stereospecific sodium salt glycosylation procedure. Glycosylation of the sodium salt of pyrrole-3-carbonitrile ( 4 ) with 1-chloro-2, 3-O-t-isopropylidene-5-O-t-butyldimethylsilyl-α-D-ribofuranose ( 5 ) gave exclusively the corresponding blocked nucleoside ( 6 ) with β-anomeric configuration, which on deprotection provided 1-β-D-ribofuranosylpyrrole-3-carbonitrile ( 7 ). Functional group tranformation of 7 gave 2 , 8c and related 3-substituted pyrrole ribonucleosides. These compounds are devoid of any significant antiviral/antitumor activity invitro.
