An efficient and convenient Cu-catalyzed three-component reaction is described for the selenation of imidazoheterocycles/indoles with Se powder and aryl iodides. This procedure provides diverse 3-arylselenylimidazoheterocycles and 3-arylselenylindoles with good yields and functional group tolerance. Some of the products exhibited better or comparable antiproliferative activities compared with the positive control 5-fluorouracil against H1975, PC-9, HGC-27, EC-109, and MCF-7 cancer cell lines.

Because enzymes can increase reaction rates by enormous factors and tend to be very specific, COA of Formula: C9H8BrN, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 10075-52-2

Several C2-methylquinazoline-based antifolates (14-26) have been prepared in which the C9,N10 bridge has been replaced by the reversed N9,C10 unit.This series was extensively studied by incorporating further substituents at N9 and C10 as well as by modifications to the p-aminobenzoate ring.The C-2-methylquinazoline analogues 29, 30, and 31 containing the methyleneoxa, methylenethia, and thia bridge units were also synthesized.In general these isosteric replacements of the bridge unit in the parent C2-methyl-N10-propargylquinazoline antifolate 2 were much less potent as inhibitors of isolated thymidylate synthase (TS) but several were at least as potent as inhibitors of L1210 cell growth in culture.The fusion of the p-aminobenzoate ring into the bicyclic systems 75 and 76 also reduced activity against TS but again gave highly cytotoxic compounds.The cytotoxicities were largely prevented by thymidine, confirming that TS in the major locus.

In our search for potential new anticancer drugs, we designed and synthesized a series of tricyclic compounds containing the antimitotic 2-phenylazaflavone chromophore fused to a pyrrole ring in a pyrroloquinoline structure. Compounds 8, 18, 19, 22, 23, 25 and 26, when tested against a panel of fourteen human tumor cell lines, showed poor in vitro cytotoxic activity, whereas 20, 21 and 24 showed significant activity (IC50 0.7 to 50 muM). Steroid hormone-sensitive ovary, liver, breast and adrenal gland adenocarcinoma cell lines displayed the highest sensitivity (IC50 0.7 to 8 muM). Compound 24 blocked cells in the G2/M phase of the cell cycle and induced a significant increase in apoptotis. Compounds 20, 21 and 24 proved to alter microtubule assembly and stability, displaying a cytoplasmic microtubule network similar to that caused by Vincristine. In vivo, administration of compound 24 to Balb/c mice inhibited the growth of a syngenic hepatocellular carcinoma.

The development of a new decarboxylative cross-coupling method that affords terminal and substituted alkynes from various carboxylic acids is described using both nickel- and iron-based catalysts. The use of N-hydroxytetrachlorophthalimide (TCNHPI) esters is crucial to the success of the transformation, and the reaction is amenable to in situ carboxylic acid activation. Additionally, an inexpensive, commercially available alkyne source is employed in this formal homologation process that serves as a surrogate for other well-established alkyne syntheses. The reaction is operationally simple and broad in scope while providing succinct and scalable avenues to previously reported synthetic intermediates.

The anti-apoptotic protein survivin is highly expressed in cancer cells but has a very low expression in fully differentiated adult cells. Overexpression of survivin is positively correlated with cancer cell resistance to chemotherapy and radiotherapy, cancer cell metastasis, and poor patient prognosis. Therefore, selective targeting survivin represents an attractive strategy for the development of anticancer therapeutics. Herein, we reported the extensive structural modification of our recently discovered selective survivin inhibitor UC-112 and the synthesis of thirty-three new analogs. The structure-activity relationship (SAR) study indicated that replacement of the benzyloxy moeity in UC-112 with an indole moiety was preferred to other moieties. Among these UC-112 analogs, 10f, 10h, 10k, 10n showed the most potent antiproliferative activities. Interestingly, they were more potent against the P-glycoprotein overexpressing cancer cell lines compared with the parental cancer cell lines. Mechanistic studies confirmed that new analogs maintained their unique selectivity against survivin among the IAP family members. In vivo study using 10f in a human A375 melanoma xenograft model revealed that it effectively inhibited melanoma tumor growth without observable acute toxicity. Collectively, this study strongly supports the further preclinical development of selective survivin inhibitors based on the UC-112 scaffold.
