Hydroaminocarbonylation of alkenes is one of the most promising yet challenging methods for the synthesis of amides. Herein, we reported the development of a novel and effective Pd-catalyzed Markovnikov hydroaminocarbonylation of 1,1-disubstituted or 1,1,2-trisubstituted alkenes with aniline hydrochloride salts to afford amides bearing an α quaternary carbon. The reaction makes use of readily available starting materials, tolerates a wide range of functional groups, and provides a facile and straightforward approach to a diverse array of amides bearing an α quaternary carbon. Mechanistic investigations suggested that the reaction proceeded through a palladium hydride pathway. The hydropalladation and CO insertion are reversible, and the aminolysis is probably the rate-limiting step.

Perez-Castillo, Yunierkis’s team published research in International Journal of Molecular Sciences in 2022 | 3959-07-7

International Journal of Molecular Sciences published new progress about Candida albicans. 3959-07-7 belongs to class bromides-buliding-blocks, and the molecular formula is C7H8BrN, SDS of cas: 3959-07-7.

Perez-Castillo, Yunierkis; Montes, Ricardo Carneiro; da Silva, Cecilia Rocha; Neto, Joao Batista de Andrade; Dias, Celidarque da Silva; Brunna Sucupira Duarte, Allana; Junior, Helio Vitoriano Nobre; de Sousa, Damiao Pergentino published the artcile< Antifungal Activity of N-(4-Halobenzyl)amides against Candida spp. and Molecular Modeling Studies>, SDS of cas: 3959-07-7, the main research area is Candida halobenzyl amide mol modeling antifungal activity; Candida auris; anticandidal drugs; antimicrobial activity; benzoic acid; candidiasis; cinnamic acid; fungi; molecular docking; natural products; plants.

Fungal infections remain a high-incidence worldwide health problem that is aggravated by limited therapeutic options and the emergence of drug-resistant strains. Cinnamic and benzoic acid amides have previously shown bioactivity against different species belonging to the Candida genus. Here, 20 cinnamic and benzoic acid amides were synthesized and tested for inhibition of C. krusei ATCC 14243 and C. parapsilosis ATCC 22019. Five compounds inhibited the Candida strains tested, with compound 16 (MIC = 7.8 μg/mL) producing stronger antifungal activity than fluconazole (MIC = 16 μg/mL) against C. krusei ATCC 14243. It was also tested against eight Candida strains, including five clin. strains resistant to fluconazole, and showed an inhibitory effect against all strains tested (MIC = 85.3-341.3 μg/mL). The MIC value against C. krusei ATCC 6258 was 85.3 mcg/mL, while against C. krusei ATCC 14243, it was 10.9 times smaller. This strain had greater sensitivity to the antifungal action of compound 16. The inhibition of C. krusei ATCC 14243 and C. parapsilosis ATCC 22019 was also achieved by compounds 2, 9, 12, 14 and 15. Computational experiments combining target fishing, mol. docking and mol. dynamics simulations were performed to study the potential mechanism of action of compound 16 against C. krusei. From these, a multi-target mechanism of action is proposed for this compound that involves proteins related to critical cellular processes such as the redox balance, kinases-mediated signaling, protein folding and cell wall synthesis. The modeling results might guide future experiments focusing on the wet-lab investigation of the mechanism of action of this series of compounds, as well as on the optimization of their inhibitory potency.
