Synthesis and Characterization of Six New Carbazolyl Porphyrins
摘要:
Novel 4-(N-carbazole methyl) benzoic acid and N-carbazolacetic acid are synthesized, then six new carbazolyl porphyrins are synthesized by bonding these acids to hydroxy porphyrin or amido porphyrin via acyl chloride or N,N'-dicyclohexylcarbodiimide (DCC)-dimethylaminopyndine methods. The formations of these title compounds, as well as their intermediates are characterized by 1H NMR, mass spectrometry, Fourier transform-infrared, and elemental analysis.
Five series of novel carbazole derivatives containing an aminoguanidine, dihydrotriazine, thiosemicarbazide, semicarbazide or isonicotinic moiety were designed, synthesised and evaluated for their antimicrobial activities. Most of the compounds exhibited potent inhibitory activities towards different bacterial strains (including one multidrug-resistant clinical isolate) and one fungal strain with minimum

In this study, a series of carbazole-rhodanine conjugates was synthesized and evaluated for their Topoisomerase II inhibition potency as well as cytotoxicity against a panel of four humancancercelllines. Among these thirteen compounds, 3a, 3b, 3g, and 3h possessed Topoisomerase II inhibition potency at 20 μM. Mechanism study revealed that these compounds may function as Topo II catalytic inhibitors
