  Aza-Peptide Analogs as Potent Human Immunodeficiency Virus Type-1 Protease Inhibitors with Oral Bioavailability

  摘要：

  A series of aza-peptide analogs with a (hydroxyethyl)hydrazine isostere has been synthesized as HIV-1 protease inhibitors using a simple synthetic scheme. Structure-activity studies based on the X-ray of a previously described inhibitor-enzyme complex led to potent inhibitors with antiviral activity in the low-nanomolar range. The S-configuration of the transition-state hydroxyl group was preferred in this series. Small modifications of the P2P3 and P-2'P-3' substituents had little effect on enzyme inhibition but greatly influenced the pharmacokinetic profile. As a result of these studies, the symmetrically acylated compound 8a and its close analog 24a bearing a methyl carbamate in P-3 and an ethyl carbamate in P-3' position were identified as potent inhibitors with plasma concentrations exceeding antiviral ED(50) values 150-fold following oral application in mice.

  Emerging yeasts are among the most prevalent causes of systemic infections with high mortality rates and there is an urgent need to develop specific, effective and non-toxic antifungal agents to respond to this issue. In this study 35 aldehydes, hydrazones and hydrazines were obtained and their antifungal activity was evaluated against Candida species (C. parapsilosis, C. tropicalis, C. krusei, C. albicans, C. glabrata and C. lusitaneae) and Trichosporon asahii, in an in vitro screening. The minimum inhibitory concentrations (MICs) of the active compounds in the screening was determined against 10 clinical isolates of C. parapsilosis and 10 of T. asahii. The compounds 4-pyridin-2-ylbenzaldehyde] (13a) and tert-butyl-(2Z)-2-(3,4,5-trihydroxybenzylidine)hydrazine carboxylate (7b) showed the most promising MIC values in the range of 16–32 μg/mL and 8–16 μg/mL, respectively. The compounds’ action on the stability of the cell membrane and cell wall was evaluated, which suggested the action of the compounds on the fungal cell membrane. Cell viability of leukocytes and an alkaline comet assay were performed to evaluate the cytotoxicity. Compound 13a was not cytotoxic at the active concentrations. These results support the discovery of promising candidates for the development of new antifungal agents.

  新兴酵母菌是系统性感染中最常见的病原体之一，死亡率极高，因此迫切需要开发具有特异性、有效且无毒的抗真菌药物来应对这一问题。本研究中，我们获得了35种醛类、肼类和酰肼类化合物，并在体外筛选中评估了它们对Candida属（C. parapsilosis、C. tropicalis、C. krusei、C. albicans、C. glabrata和C. lusitaneae）和Trichosporon asahii的抗真菌活性。我们对筛选出的活性化合物对10株临床分离的C. parapsilosis和10株T. asahii的最低抑菌浓度（MICs）进行了测定。化合物4-吡啶-2-基苯甲醛（13a）和叔丁基-(2Z)-2-(3,4,5-三羟基苄脒)酰肼羧酸酯（7b）分别在16-32 μg/mL和8-16 μg/mL的范围内显示出最有希望的MIC值。我们评估了这些化合物对细胞膜和细胞壁稳定性的影响，结果表明这些化合物作用于真菌细胞膜。通过细胞活力测定和碱性彗星试验评价了其细胞毒性。化合物13a在活性浓度下不具有细胞毒性。这些结果支持了发现有希望的候选药物用于开发新型抗真菌药物。
