Synthesis and antiproliferative activity of thiazolyl-bis-pyrrolo[2,3-b]pyridines and indolyl-thiazolyl-pyrrolo[2,3-c]pyridines, nortopsentin analogues

Two new series of nortopsentin analogues, in which the imidazole ring of the natural product was replaced by thiazole and indole units were both substituted by 7-azaindole moieties or one indole unit was replaced by a 6-azaindole portion, were efficiently synthesized. Compounds belonging to both series inhibited the growth of HCT-116 colorectal cancer cells at low micromolar concentrations, whereas they did not affect the viability of normal-like intestinal cells. A compound of the former series induced apoptosis, evident as externalization of plasma membrane phosphatidylserine (PS), and changes of mitochondrial trans-membrane potential, while blocking the cell cycle in G2/M phase. In contrast, a derivative of the latter series elicited distinct responses in accordance with the dose. Thus, low concentrations (GI30) induced morphological changes characteristic of autophagic death with massive formation of cytoplasmic acid vacuoles without apparent loss of nuclear material, and with arrest of cell cycle at the G1 phase, whereas higher concentrations (GI70) induced apoptosis with arrest of cell cycle at the G1 phase.

Synthesis and antiproliferative activity of substituted 3[2-(1h-indol-3-yl)- 1,3-thiazol-4-yl]-1h-pyrrolo[3,2-b]pyridines, marine alkaloid nortopsentin analogues

A large number of indolyl-4-azaindolyl thiazoles, nortopsentin analogues, were conveniently synthesized. The antiproliferative activity of the new derivatives was examined against four human tumor cell lines with different histologic origin. Seven derivatives consistently reduced the growth of the experimental models independently of TP53 gene status and exhibited the highest activity against the malignant peritoneal mesothelioma (STO) cell line. The most active compound of this series acts as a CDK1 inhibitor, and was found to cause cell cycle arrest at G2/M phase, to induce apoptosis by preventing the phosphorylation of survivin in Thr34 and to increase the cytotoxic activity of paclitaxel in STO cells.

Novel 1H-pyrrolo[2,3-b]pyridine derivative nortopsentin analogues: Synthesis and antitumor activity in peritoneal mesothelioma experimental models

In this study, we describe the synthesis of new nortopsentin analogues, 1H-pyrrolo[2,3-b]pyridine derivatives and their biological effects in experimental models of diffuse malignant peritoneal mesothelioma (DMPM), a rare and rapidly fatal disease, poorly responsive to conventional therapies. The three most active compounds, 1f (3-[2-(5-fluoro-1-methyl-1H-indol-3-yl)-1,3- thiazol-4-yl]-1H-pyrrolo[2,3-b]pyridine), 3f (3-[2-(1H-indol-3-yl)-1,3-thiazol- 4-yl]-1-methyl-1H-pyrrolo[2,3-b]pyridine), and 1l (3-[2-(5-fluoro-1-methyl-1H- indol-3-yl)-1,3-thiazol-4-yl]-1-methyl-1H-pyrrolo[2,3-b] pyridine), which were shown to act as cyclin-dependent kinase 1 inhibitors, consistently reduced DMPM cell proliferation and induced a caspase-dependent apoptotic response, with a concomitant reduction of the expression of the active Thr34- phosphorylated form of the antiapoptotic protein survivin. Moreover, the combined treatment of DMPM cells with 3f derivative and paclitaxel produced a synergistic cytotoxic effect, which was paralleled by an enhanced apoptotic response. In the mouse model, i.p. administration of 1f, 3f, and 1l derivatives was effective, resulting in a significant tumor volume inhibition of DMPM xenografts (range, 58-75%) at well-tolerated doses, and two complete responses were observed in each treatment group.

Designer phytoalexins: Probing camalexin detoxification pathways in the phytopathogen Rhizoctonia solani

To probe the specificity of a camalexin detoxifying enzyme(s) produced by Rhizoctonia solani, the putative 5-camalexin hydroxylase (5-CAHY), the naturally occurring phytoalexin 1-methylcamalexin and designer phytoalexins in which the H-5 of camalexin was replaced with either a methyl group or a fluorine atom were synthesised. This investigation showed that biotransformation of 5-fluorocamalexin by R. solani was substantially slower than that of camalexin (12 days vs. six to eight hours), 5-methylcamalexin (5-6 days) or 1-methylcamalexin (5-6 days). Antifungal bioassays showed that 5-fluorocamalexin, 5-methylcamalexin and 1-methylcamalexin were more inhibitory to R. solani than camalexin, whereas their metabolic products displayed substantially lower inhibitory activity. It was concluded that detoxification via oxidation of the indole moiety of camalexins is predominant in the biotransformation of both camalexin and 5-methylcamalexin and likely catalysed by a specific 5-CAHY. By contrast, the pathways for detoxification of 1-methylcamalexin and 5-fluorocamalexin are likely catalysed by non-specific house-keeping enzymes. Most importantly, because 1-methylcamalexin showed stronger antifungal activity and was metabolised at substantially slower rate than camalexin this work suggested that, from a plant's perspective 1-methylcamalexin could be a more effective antifungal defence than camalexin.
