Flexible dimeric substituted pyridinium bromides with primary and tertiary amines are prepared by conventional and solvent-free methods. The formation of compounds 2 and 4 is much easier than that of compounds 1 and 3 because of the benzyl carbon which is more electropositive than the primary alkyl carbon. The newly synthesized dimeric pyridinium compounds are optimized using p). The in vitro antiproliferative activity is studied in lung (A549) and breast cancer cell lines (MDA-MB 231). Among the four compounds, 1,1′-(1,3-phenylene bis(methylene)bis 2aminopyridinium bromide 4 showed potent anticancer activity when compared to the standard drug 5-fluorouracil. 1,1′-(1,3-Phenylene bis(methylene)bis 2aminopyridinium bromide 4 is not toxic to normal cell lines 3T3-L1 and MRC-5 cell lines. Also, 1,1′-(1,3-phenylene bis(methylene)bis 2-aminopyridinium bromide 4-induced apoptosis in cancer cell lines is examined using AO/EB and Hoechst staining, which is further supported by cell cycle analysis. Western blot analysis showed that 1,1′-(1,3-phenylene bis(methylene)bis 2-aminopyridinium bromide 4 induces apoptosis through the extrinsic apoptotic pathway by upregulating caspase 3 and caspase 9. This compound also downregulates intrinsic apoptotic proteins, including Bcl-2, Bcl-x, and Bad. From the present study results, it is confirmed that 1,1′-(1,3-phenylene bis(methylene)bis 2aminopyridinium bromide 4 has potent anticancer activity when compared to other compounds.

Synthesis of phenyl/benzothiazole functionalized C−C linked pyrazolyl‐thiazoles has been achieved from non‐lachrymatory α‐tosyloxy pyrazolylketones with different thioamides. The pyrazolyl‐thiazoles were characterized by spectroscopic studies and evaluated for antimicrobial activity and phytotoxicity. Compound 6 n displayed better activity with MIC value of 0.0045 μmol/mL against Gram‐positive bacteria B. cereus in comparison to the standard drug Ciprofloxacin (0.0047 μmol/mL). Compound 6 i displayed better activity against fungal strain C. albicans (MIC=0.0152 μmol/mL) in comparison to the standard drug Fluconazole (0.0204 μmol/mL). Compound 6 o diplayed 95 % cell viability against Mouse Fibroblast cell line and 100 % plant seed germination. Docking studies at the topoisomerase II DNA gyrase B (PDB ID: 1KZN) and C. albicans (PDB ID: 1IYL) were used to investigate potential interactions between the most active compound and the receptor protein. The stability of the compounds with 1KZN and 1IYL by molecular dynamic simulations showed that 6 r, 6 n and 6 i present leading structures for next drug development because of their simple synthesis and useful bioactivity.
