Synthesis of some novel dimethine,bis-dimethine cyanine dyes and octacosamethine cyanine dyes endowed with promising biological potency against (HepG2), (Hela), (MCF-7), (MIA), (SN12C) and (H358) cell lines

Successfully, one step two component synthesis of dimethine cyanine dyes, bis-dimethine cyanine dyes and icosamethine cyanine dyes 2–10via reaction of pyridinium salt 1 with some different aldehydes hope to obtain these compounds with enhanced biological potency as antitumor agents against spontaneous liver (HepG2), cervical (Hela), breast (MCF-7), pancreas (MIA), kidney (SN12C) and lung (H358). The impact of substituted drugs on the tumor cells was reflected by means of structure activity relationship (SAR). Among these dyes, icosamethine cyanine dye 8 recorded an excellent activity toward all the tested cell lines. The newly destined drugs were identified and emphasized by spectroscopy and elemental analyses.
