is more than 900-fold selective for mGlu5 versus the other mGlu receptors, and binding studies established a Ki value of 4.4 nM at a known allosteric binding site. Compound 27 had a clearance of 19.3 and 15.5 mL/min/kg in rats and cynomolgus monkeys, respectively. Imaging studies using a known mGlu5 PET ligand demonstrated 50% receptor occupancy at an oral dose of 0.8 mg/kg in rats and an intravenous
支持mGlu 5 NAM在治疗各种精神病和神经退行性疾病中的潜在效用的临床前证据是广泛的,并且许多此类分子已进入临床试验。尽管临床研究取得了令人鼓舞的结果,但尚无小分子mGlu 5 NAM进入市场。在这里,我们介绍N-(5-氟吡啶-2--2-基)-6-甲基-4-(嘧啶-5-基氧基)吡啶啉酰胺(27,VU0424238)的发现和评估,该化合物是用于临床评估的化合物。化合物27是用于组mGlu超过900倍的选择性5相对于其他mGlu受体,和结合研究建立了ķ我在已知的变构结合位点处的值为4.4nM。化合物27在大鼠和食蟹猴中的清除率分别为19.3和15.5 mL / min / kg。使用已知的mGlu 5 PET配体进行的影像学研究表明,大鼠口服剂量为0.8 mg / kg,狒狒静脉注射剂量为0.06 mg / kg时,受体占有率为50%。
Design, Synthesis, and Biological Evaluation of Novel Pyrimido[4,5-<i>b</i>]indole Derivatives Against Gram-Negative Multidrug-Resistant Pathogens
potent activity against Gram-negative pathogens have been reported. Among them, pyrimido[4,5-b]indole derivatives represented by GP-1 demonstrated excellent broad-spectrum antibacterial activity against both Gram-positive and Gram-negative bacteria but were limited by hERG inhibition and poor pharmacokinetics profile. To improve their drug-like properties, we designed a series of novelpyrimido[4,5-b]indole
由于革兰氏阴性细菌膜的渗透性差和细菌外排机制麻烦,因此仅报道了少数对革兰氏阴性病原体具有有效活性的 GyrB/ParE 抑制剂。其中,以GP-1为代表的嘧啶并[4,5- b ]吲哚衍生物对革兰氏阳性菌和革兰氏阴性菌均表现出优异的广谱抗菌活性,但受到hERG抑制和较差的药代动力学特征的限制。为了改善它们的类药物特性,我们设计了一系列基于 GP-1 的三环支架和阿卡沙星的 C-7 部分的新型嘧啶并 [4,5- b ] 吲哚衍生物。这些努力最终导致了有希望的化合物18r的发现减少 hERG 责任和改善 PK 概况。化合物18R表现出优异的广谱体外相比GP-1的抗菌活性,包括各种临床耐药的G -病原体,尤其是鲍曼不动杆菌,并且在体内的功效还证实在中性粒细胞减少一个小鼠感染的多药大腿模型耐药鲍曼不动杆菌。
