  双功能桦木酸衍生物的合成及其抗HIV活性。

  摘要：

  在C-3处带有侧链的桦木酸（BA）衍生物可以抑制HIV-1的成熟。另一方面，在C-28带有侧链的BA衍生物可以阻止HIV-1进入。为了在单个分子中结合抗成熟和抗进入活性，已经合成了在C-3和C-28处含有侧链的新的双功能BA衍生物。最有效的化合物（[[[N- [3beta-O-（3'，3'-二甲基琥珀酰基）-lup-20（29）-en-28-oyl] -7-氨基庚基] -carba moyl]甲烷抑制HIV -1在EC26为0.0026 microM时，效力至少是抗成熟铅化合物DSB或抗进入铅化合物IC9564的20倍。这种双功能BA衍生物对HIV的进入和成熟均具有活性。

  Antimicrobial properties of amine- and guanidine-functionalized derivatives of betulinic, ursolic and oleanolic acids: Synthesis and structure/activity evaluation

  摘要：

  A series of 34 new amine- and guanidine-functionalized derivatives of betulinic, ursolic, and oleanolic acids were synthesized and tested for their antimicrobial activity against the growth of four bacterial strains (Escherichia colt Acinetobacter baumannii, Pseudomonas aeruginosa, and Staphylococcus aureus (MESA)) and two fungal strains (Candida albicans and Cryptococcus neoformans). The obtained compounds were also tested for the cytotoxic effect against HEK293 human embryonic kidney cell line and hemolytic activity against human red blood cells. Most of the prepared amino and guanidinium derivatives of betulinic, ursolic, and oleanolic acids showed a considerably higher bacteriostatic activity against methicillin-resistant S. aureus than the parent compounds. The most active compounds (MICs <= 0.25 mu g/ml or 0.4-0.5 mu M) were superior over the clinically used antibiotic vancomycin in the antibacterial effect (MIC of 1 mu g/ml or 0.7 mu M). Apart from antibacterial activity, new triterpene acid derivatives exhibited excellent antifungal activity against Cryptococcus neoformans, with MICs values being as low as 0.25 mu g/ml (0.4 mu M), and were approximately 65 times as active as fluconazole, a known antifungal agent. Four most promising compounds we identified (7, 13, 24, and 33) showed not only high bacteriostatic effect, but also low cytotoxicity against mammalian HEK293 cells and high hemolytic selectivity.

• Synthesis of betulinic acid derivatives as entry inhibitors against HIV-1 and bevirimat-resistant HIV-1 variants

  Betulinic acid derivatives modified at the C28 position are HIV-1entry inhibitors such as compound A43D; however, modified at the C3 position instead of C28 give HIV-1 maturation inhibitor such as bevirimat. Bevirimat exhibited promising pharmacokinetic profiles in clinical trials, but its effectiveness was compromised by the high baseline drug resistance of HIV-1 variants with polymorphism in the putative drug binding site. In an effort to determine whether the viruses with bevirimat resistant polymorphism also altered their sensitivities to the betulinic acid derivatives that inhibit HIV-1 entry, a series of new betulinic acid entry inhibitors were synthesized and tested for their activities against HIV-1 NL4-3 and NL4-3 variants resistant to bevirimat. The results show that the bevirimat resistant viruses were approximately 5- to10-fold more sensitive to three new glutamine ester derivatives (13, 15 and 38) and A43D in an HIV-1 multi-cycle replication assay. In contrast, the wild type NL4-3 and the bevirimat resistant variants were equally sensitive to the HIV-1 RT inhibitor AZT. In addition, these three new compounds markedly improved microsomal stability compared to A43D. (c) 2012 Elsevier Ltd. All rights reserved.

  Bevirimat (1, BVM) is an anti-HIV agent that blocks HIV-1 replication by interfering with HIV-1 Gag-SP1 processing at a late stage of viral maturation. However, clinical trials of 1 have revealed a high baseline drug resistance that is attributed to naturally occurring polymorphisms in HIV-1 Gag. To overcome the drug resistance, 28 new derivatives of 1 were synthesized and tested against compound 1-resistant (BVM-R) HIV-1 variants. Among them, compound 6 exhibited much improved activity against several HIV-1 strains carrying BVM-R polymorphisms. Compound 6 was at least 20-fold more potent than 1 against the replication of NL4-3/V370A, which carries the most prevalent clinical BVM-R polymorphism in HIV-1 Gag-SP1. Thus, compound 6 merits further development as a potential anti-AIDS clinical trial candidate.

  We previously reported that [[N-[3 beta-hydroxyllup-20(29)-en-28-oyl]-7-aminoheptyl]carbamoyl]methane (A43D, 4) was a potent HIV-1 entry inhibitor. However, 4 was inactive against HIV-2 virus, suggesting the structural requirements for targeting these two retroviruses are different. In this study, a series of new betulinic acid derivatives were synthesized, and some of them displayed selective anti-HIV-2 activity at nanomolar concentrations. In comparison to compounds with anti-HIV-1 activity, a shorter C-28 side chain is required for optimal anti-HIV-2 activity.
