  通过卡莫氟结构引导的命中到先导优化发现抗病毒 SARS-CoV-2 主要蛋白酶抑制剂

  摘要：

  严重急性呼吸综合征冠状病毒 2 (SARS-CoV-2) 主要蛋白酶 (M pro ) 已成为开发针对 COVID-19 感染的抗 SARS-CoV-2 药物的目标，因为 M pro处理必需的病毒多蛋白并发挥关键作用在 SARS-CoV-2 复制中的作用。在这项研究中，我们报告了源自卡莫氟的新型 SARS-CoV-2 M pro抑制剂的开发，卡莫氟是一种先前鉴定的化合物，作为 SARS-CoV-2 M pro的共价抑制剂显示出中等效力。为了采用结构引导的药物设计策略，首先通过对接模拟预测了卡莫氟在 M pro催化活性位点上的假定完整结合模式。基于预测的结合模式，对一系列旨在占据M pro底物结合区域的卡莫氟衍生物进行了构效关系分析。结果， 发现了一种基于吲哚的衍生物，推测与 S4 结合袋相互作用， 21b (IC 50 = 1.5 ± 0.1 μM)。通过结合对接模拟、自由能扰动计算和子口

  N-Alkenyl and cycloalkyl carbamates as dual acting histamine H3 and H4 receptor ligands

  摘要：

  Previous studies have shown that several imidazole derivatives posses affinity to histamine H-3 and H-4 receptors. Continuing our study on structural requirements responsible for affinity and selectivity for H-3/H-4 receptor subtypes, two series of 3-(1H-imidazol-4-yl) propyl carbamates were prepared: a series of unsaturated alkyl derivatives (1-9) and a series possessing a cycloalkyl group different distances to the carbamate moiety (10-13). The compounds were tested for their affinities at the human histamine H3 receptor, stably expressed in CHO-K1 cells. Compounds 1, 2, 5-7, 10-13 were investigated for their affinities at the human histamine H-4 receptor co-expressed with G alpha(i2) and G beta(1)gamma(2) subunits in Sf9 cells. To expand the pharmacological profile, compounds were further tested for their H3 receptor antagonist activity on guinea pig ileum and in vivo after oral administration to mice. All tested compounds exhibited good affinity for the human histamine H-3 receptor with K-i values in the range from 14 to 194 nM. All compounds were active in vivo after peroral administration (p.o.) to Swiss mice, thus demonstrating their ability to cross the blood-brain barrier. The most potent H-3 receptor ligand of these series was compound 5, 3-(1H-imidazol-4-yl) propyl pent-4-enylcarbamate with the highest affinity (K-i = 14 nM). Additionally, compound 3 showed remarkable central nervous system (CNS) H3R activity, increasing the N-tau-methylhistamine levels in mice with an ED50 value of 0.55 mg/kg, p.o. evidencing therefore, a twofold increase of inverse agonist/antagonist potency compared to the reference inverse agonist/antagonist thioperamide. In this study, the imidazole propyloxy carbamate moiety was kept constant. The different lipophilic moieties connected to the carbamate functionality in the eastern part of the molecule had a range of influences on the human H-4 receptor affinity (154-1326 nM).

  Fifty-four 1-carbamoyl-5-fluorouracils were synthesized from 5-fluorouracil and isocyanate or amine. Antitumor activity was tested in the L-1210 tumor system, and 11 compounds gave better values of therapeutic ratio than HCFU (1-hyxylcarbamoyl-5-fluorouracil). 1-(4-Methoxycyclohexylcarbamoyl)-5-fluorouracil gave the best result.

  Various 3-substituted derivatives of 1-(p-vinylbenzenesulphonyl)urea, 1-[p-(2-chloroethyl)benzenesulphonyl]urea and 1-[p-(2-bromoethyl)benzenesulphonyl]urea are described. Several of the compounds possess noteworthy hypoglycaemic activity on oral administration in rabbits. In contrast, several related 5-substituted derivatives of 2-[p-(2-chloroethyl)benzenesulphonamido]-1,3,4-thiadiazoles and -1,3,4-oxadiazoles were virtually inactive.

  A new class of chiral ruthenium catalysts is introduced in which ruthenium is cyclometalated by two 7-methyl-1,7-phenanthrolinium heterocycles, resulting in chelating pyridylidene remote N-heterocyclic carbene ligands (rNHCs). The overall chirality results from a stereogenic metal center featuring either a Λ or Δ absolute configuration. This work features the importance of the relative metal-centered
