In the current study, a new series of 1,2,3-triazole derivatives was synthesized via copper (I) catalyzed azide-alkyne cycloaddition reaction using a series of synthesised p-substituted phenyl azides and propiolic acid. In addition, a new series of hetero

Macrolides are widely prescribed in clinic to treat various respiratory tract infections. However, due to their inappropriate use, the prevalence of macrolide-resistant strains among clinical isolates has become a concern for public health. Therefore, nov

A series of novel oridonin derivatives bearing various substituents on the 14-OH position were designed and synthesised. Their antitumour activity was evaluated in vitro against three human cancer cell lines (HCT116, BEL7402, and MCF7). Most tested derivatives showed improved anti-proliferative activity compared to the lead compound oridonin and the positive control drug 5-fluorouracil (5-Fu). Among them, compound C7 (IC50 = 0.16 μM) exhibited the most potent anti-proliferative activity against HCT116 cells; it was about 43- and 155-fold more efficacious than that of oridonin (IC50 = 6.84 μM) and 5-Fu (IC50 = 24.80 μM) in HCT116 cancer cells. Interestingly, the IC50 value of compound C7 in L02 normal cells was 23.6-fold higher than that in HCT116 cells; it exhibited better selective anti-proliferative activity and specificity than oridonin and 5-Fu. Furthermore, compound C7 possibly induced cell cycle arrest and apoptosis by regulating the p53-MDM2 signalling pathway. Notably, C7 displayed more significant suppression of tumour growth than oridonin in colon tumour xenograft models where the tumour growth inhibition rate was 85.82%. Therefore, compound C7 could be a potential lead compound for the development of a novel antitumour agent.

Hsp90 C-terminal inhibitors are advantageous for the development of new cancer chemotherapeutics due to their ability to segregate client protein degradation from induction of the prosurvival heat shock response, which is a major detriment associated with
Boronic acid catalysis for mild and selective [3+2] dipolar cycloadditions to unsaturated carboxylic acids
Zheng, Hongchao,McDonald, Robert,Hall, Dennis G.
experimental part, p. 5454 - 5460 (2010/09/15)
Herein, the concept of boronic acid catalysis (BAC) for the activation of unsaturated carboxylic acids is applied in several classic dipolar [3 + 2] cycloadditions involving azides, nitrile oxides, and nitrones as partners. These cycloadditions can be used to produce pharmaceutically interesting, small heterocyclic products, such as triazoles, isoxazoles, and isoxazolidines. These cycloadducts are formed directly and include a free carboxylic acid functionality that can be employed for fur-ther transformations, thereby avoiding prior masking or functionalization. In all cases, BAC provides faster reactions, under milder conditions, with much improved product yields and regioselectivities. In some instances, such as triazole formation from the reaction of azides with 2-alkynoic acids, catalysis with ort/io- nitrophenylboronic acid circumvents the undesirable product decarboxylation observed when using thermal activation. By using NMR spectroscopic studies, the boronic acid catalyst was shown to provide activation by a LUMO-lowering effect in the unsaturated carboxylic acid, likely via a monoacylated hemiboronic ester intermediate.
