  Conjugates of 3α-methoxyserrat-14-en-21β-ol (PJ-1) and 3β-methoxyserrat-14-en-21β-ol (PJ-2) as cancer chemopreventive agents

  摘要：

  3 alpha-Methoxyserrat-14-en-21 beta-ol (PJ-1) and 3 beta-methoxyserrat-14-en-21 beta-ol (PJ-2) were conjugated with well-known phenolic compounds, narigenin, hesperetin, genistein, and daidzein (1-8). Other conjugates of PJ-2-3,5-dihydroxy-4-methoxybenzoic acid (9), PJ-2 pyrogallol (10), and derivatives of PJ-1, PJ-2-3,3-dimethyl-succinates (11, 12), PJ-1, PJ-2 succinates (13, 14), PJ-2 glycine (15), PJ-2 piperidine acetic acid (16), and PJ-1 epoxy-3,3-dimethyl-succinate (17) were tested for their inhibitory effects on Epstein Barr virus early antigen (EBV-EA) activation induced by 12-O-tetradecanoylphorbol-13-acetate (TPA). The inhibitory effects of 11 (IC50 = 251),12 (IC50 = 248), and 17 (IC50= 230 mol ratio/32 pmol/TPA), were 2-fold stronger than those of the other compounds such as oleanolic acid (IC50 = 449). Compounds 10, 11, and 17 inhibited mouse skin tumor promotion in an in vivo two-stage carcinogenesis model. The in vivo two-stage mouse-skin carcinogenesis test employed 7,12-dimethylbenz[a]anthracene (DMBA) as an initiator and TPA as a promoter. (C) 2011 Elsevier Masson SAS. All rights reserved.

  Eight neutral triterpenes have been isolated from Sitka spruce bark. These compouds were shown to belong to the unique serratenediol family in which ring C is 7-membered. The two major components have the structure 3β-methoxy-21β-hydroxy-Δ14-serratene (VIII) and the corresponding 3α isomer (IX). A third compound was found to be 3α-methoxy-21β-hydroxy-Δ13-serratene (XXIII) which is the first reported

  Two new serratane-type triterpenoids, 1 and 2, were isolated from the stem bark of Picea jezoensis Carr. var. jezoensis (Pinaceae). Their structures were determined to be 3beta-methoxyserrat-13-en-21beta-ol (1) and 13beta, l4beta-epoxy-3beta-methoxyserratan-21beta-ol (2) on the basis of spectroscopic methods and partial syntheses. Compounds 1 and 2 and their acetates were screened as potential anti-tumor

  从云杉云杉的茎皮中分离出两个新的Serratane型三萜类化合物1和2。变种 jezoensis（木犀科）。根据光谱方法和部分合成，确定它们的结构为3beta-甲氧基serrat-13-en-21beta-ol（1）和13beta，14beta-环氧-3beta-甲氧基塞拉坦-21beta-ol（2）。通过使用体外短期12-O-十四烷酰佛波醇13-乙酸盐（TPA）诱导的爱泼斯坦-巴尔病毒早期抗原（EBV-EA）活化测定，筛选化合物1和2及其乙酸盐作为潜在的抗肿瘤启动子。IC50值评估表明化合物1比其他化合物更有效。另外，在由7诱导的小鼠皮肤肿瘤的两阶段致癌试验中，检查了化合物1和2的抗肿瘤促进活性。12-二甲基苯并[a]蒽（DMBA）作为引发剂，TPA作为促进剂。化合物1和2对小鼠皮肤癌变具有显着的抗肿瘤促进作用。

  3 alpha-Methoxyserrat-14-en-21 beta-ol (1) and 3 beta-methoxyserrat-14-en-21 beta-ol (2) and their conjugates with curcumin, kojic acid, quercetin, and baicalein (3-18), as well as new analogs (19-24) derived from 1 and 2, were tested for their inhibitory effects on Epstein-Barr virus early antigen (EBV-EA) activation induced by 12-O-tetradecanoylphorbol-13-acetate (TPA). The inhibitory effects of 16 (IC50= 330 mol ratio/32 pmol/TPA). 9 (IC50=335), 10 (IC50= 338), and 15 (IC50= 350) were stronger than those of the other compounds and the positive control, oleanolic acid (IC50= 449). Compounds 15 and 16, which are conjugates of one molecule each of 1 or 2 and quercetin, inhibited mouse skin tumor promotion in an in vivo two-stage carcinogenesis model. The in vivo two-stage mouse skin carcinogenesis test employed 7,12-dimethylbenz[a]anthracene (DMBA) as an initiator and TPA as a promoter.

  Sixteen novel compounds; 3 alpha-methoxyserrat-14-en-21 beta-ol (1) and 3 beta-methoxyserrat-14-en-21 beta-ol (2) and their curcumin, kojic acid, quercetin, and baicalein conjugates (3)-(18) were designed, synthesized, and evaluated for in vitro anti-HIV-1 reverse transcriptase (RT) activity in infected C8166-CCR5 cells, a human CD4(+) T-lymphocyte cell line. Among them, kojic acid derivatives, 9-12 showed significant biological activity. In particular, the compound 13, the conjugate of two molecules of 3 alpha-methoxyserrat-14-en-21 beta-ol (1) and one molecule of kojic acid, exerted significant anti-HIV activity with an EC50 value of 0.12 mu g/mL.
