Optimization of Novel 1-Methyl-1H-Pyrazole-5-carboxamides Leads to High Potency Larval Development Inhibitors of the Barber’s Pole Worm
摘要:
A phenotypic screen of a diverse library of small molecules for inhibition of the development of larvae of the parasitic nematode Haemonchus contortus led to the identification of a 1-methyl-1H-pyrazole-5-carboxamide derivative with an IC50 of 0.29 mu M. Medicinal chemistry optimization targeted modifications on the left-hand side (LHS), middle section, and right-hand side (RHS) of the scaffold in order to elucidate the structure-activity relationship (SAR). Strong SAR allowed for the iterative and directed assembly of a focus set of 64 analogues, from which compound 60 was identified as the most potent compound, inhibiting the development of the fourth larval (L4) stage with an IC50 of 0.01 mu M. In contrast, only 18% inhibition of the mammary epithelial cell line MCF10A viability was observed, even at concentrations as high as 50 mu M.
在重要的化学反应中具有高活性和选择性的纳米结构和可重复使用的 3d 金属催化剂是非常需要的。在这里,开发了一种钴催化剂,用于通过还原胺化反应合成伯胺,使用氢气作为还原剂,易处理的氨水溶解在水中,作为氮源。催化剂在非常温和的条件下运行(1.5 mol% 催化剂负载,50 °C 和 10 bar H 2压力)并优于市售的贵金属催化剂(Pd、Pt、Ru、Rh、Ir)。观察到广泛的范围和非常好的官能团耐受性。高活性的关键似乎是使用的载体:一种 N 掺杂的无定形碳材料,具有小的和乱层无序的石墨域,它是微孔的,具有双峰尺寸分布,并且在孔中具有基本的 NH 官能团。

Nanostructured and reusable 3d-metal catalysts that operate with high activity and selectivity in important chemical reactions are highly desirable. Here, a cobalt catalyst was developed for the synthesis of primary amines via reductiveamination employing hydrogen as the reducing agent and easy-to-handle ammonia, dissolved in water, as the nitrogen source. The catalyst operates under very mild conditions

The invention provides molecular entities that bind with high affinity to PPARG (PPARϒ), inhibit cdk5-mediated phosphorylation of PPARG, but do not exert an agonistic effect on PPARG. Compounds of the invention can be used for treatment of conditions in patients wherein PPARG plays a role, such as diabetes or obesity. Methods of preparation of the compounds, bioassay methods for evaluating compounds of the invention as non-agonistic PPARG binding compounds, and pharmaceutical compositions are also provided.

A copper-catalyzed route to α-substituted, primarybenzylamines by C–H functionalization of alkylarenes is described. The method directly affords the amine hydrochloride salt. Catalyst loadings down to 0.1 mol % in combination with scalability, insensitivity to air and moisture, and no need for column chromatography makes the procedure highly practical. The facile synthesis of the racemate of a blockbuster
