Synthesis and Antimicrobial Evaluation of Some New Dihydropyridine, Pyrazole, Chromene, Pyrrole, Thiazole and Thiophene Derivatives
摘要:
Synthesis of 2-cyano-N((2-methoxynaphthalen-1-yl)methylene)acetohydrazide (3) and its use as a key intermediate for the synthesis of some new heterocyclic compounds such as dihydropyridines (4, 6 and 8), pyrazoles (9 and 10), chromene (11), pyrroles (12 and 13), thiazoles (14 and 17) and thiophene (18-20) derivatives were described. The structures of newly synthesized compounds have been established on the basis of their IR, H-1-NMR, C-13-NMR and mass spectral data and have been screened for their antimicrobial activity.

of pyrazole, 1,2,4‐triazine, isoxazole, pyrimidine, and other related products containing a hydrazide moiety were prepared via the reaction of 2‐cyano‐N‐((2‐methoxynaphthalen‐1‐yl)methylene) acetohydrazide (1) with appropriate chemical reagents. These compounds were evaluated for their antimicrobial activities, and also their minimum inhibitory concentration against most of test organisms was performed

The reaction of 2-cyano-3-(dimethylamino)-N-((2-methoxynaphthalen-1-yl)methylene)acrylohydrazide (2) with some nitrogen nucleophiles, phenols and compounds, having an active methylene group to obtain polyfunctionally substituted azoles (3-5), azine (6), fused azines (7-10) and fused pyran-2-one derivatives (11-17). All the synthesized products were confirmed by elemental analysis, IR, H-1-NMR,13C-NMR and MS data. The antitumor evaluation of the newly synthesized products against four human tumor cells lines namely hepatocellular carcinoma (liver) HepG-2, colorectal carcinoma (colon) HCT-116, mammary gland (breast) MCF-7 and epidermoid carcinoma (larynx) Hep-2 was investigated. Compound 4 exhibited superior in vitro antitumor activity in the 3-cell lines assay.
