A small family of structural analogues of the antimitotic tripeptides, hemiasterlins, have been designed and synthesized as potential inhibitors of tubulin polymerization. The effectiveness of a multicomponent approach was fully demonstrated by applying complementary versions of the isocyanide-based Ugi reaction. Compounds strictly related to the lead natural products, as well as more extensive...
Compounds originally designed as putative tubulin inhibitors were tested as antitubercular agents for inhibition of the Mycobacterium tuberculosis analogue of tubulin, FtsZ. Initial screening of 200 2-alkoxycarbonylpyridines found several that inhibited M. tuberculosis growth. Two compounds, SRI-3072 and SRI-7614, inhibited FtsZ polymerization and were equipotent against susceptible and single-...
We synthesized 3-aroyl-1-arylpyrrole (ARAP) derivatives as potential anticancer agents having different substituents at the pendant 1-phenyl ring. Both the 1-phenyl ring and 3-(3,4,5-trimethoxyphenyl)carbonyl moieties were mandatory to achieve potent inhibition of tubulin polymerization, binding of colchicine to tubulin, and cancer cell growth. ARAP 22 showed strong inhibition of the P-glycopro...
A library of imidazopyrimidine-propenone conjugates (8a-8g) were synthesized and evaluated for their antitumor activity against three human cancer cell lines namely prostate (DU-145), lung (A549) and breast (MCF-7) cancer. These conjugates showed good to moderate activity against the tested cell lines. Among them two conjugates (8c and 8d) showed significant antiproliferative activity against h...
background: tubulin protein being the fundamental unit of microtubules is actively involved in cell division thus making them a potential anti-cancer drug target. in spite of many reported drugs against tubulin, few of them have started developing resistance in human β-tubulin due to amino acid substitutions. methods: in this study we generated three mutants (f270v, a364t and q292e) using model...
A variety of commercial analogs and a newer series of Sulindac derivatives were screened for inhibition of M. tuberculosis (Mtb) in vitro and specifically as inhibitors of the essential mycobacterial tubulin homolog, FtsZ. Due to the ease of preparing diverse analogs and a favorable in vivo pharmacokinetic and toxicity profile of a representative analog, the Sulindac scaffold may be useful for ...
The antimitotic depsipeptide dolastatin 15 was radiolabeled with tritium in its amino-terminal dolavaline residue. Dolastatin 15, although potently cytotoxic, is a relatively weak inhibitor of tubulin assembly and does not inhibit the binding of any other ligand to tubulin. The only methodology found to demonstrate an interaction between the depsipeptide and tubulin was Hummel-Dreyer equilibriu...
