23-Hydroxyursolic acid (2), previously isolated from medicinal plants of the Rubiaceae family, was synthesized in ten steps via methyl 23-hydroxy-3-oxours-12-en-28-oate (5) from commercially available ursolic acid (6).

以前从茜草科药用植物中分离出的 23-羟基熊果酸（2）是通过 23-hydroxy-3-oxours-12-en-28-oate (5) 从市售熊果酸（6）中分十步合成的。

A specific inhibitor of DNA cytosine C5-methylases would be useful for studying genomic imprinting, X-chromosome inactivation, carcinogenesis, and regulation of tissue-specific gene expression, for these physiological phenomena appears to be regulated through DNA methylation in promoter sequences. This paper reports a novel convenient in vitro assay method for screening DNA cytosine C5-methylase inhibitor. Our method uses a commercially available Hae III methylase (cytosine C5 methylase), its corresponding Hae III endonuclease, and u DNA as their substrate.
DNA胞嘧啶c5甲基化酶的特异性抑制剂将有助于研究基因组印迹、x染色体失活、癌变和组织特异性基因表达的调控，因为这些生理现象似乎是通过启动子序列中的DNA甲基化来调节的。本文报道了一种新的体外筛选DNA胞嘧啶c5 -甲基化酶抑制剂的简便方法。我们的方法使用市售的Hae III甲基化酶(胞嘧啶C5甲基化酶)，其相应的Hae III内切酶和u DNA作为底物。

Extraction Studies of Tabernanthe Iboga and Voacanga Africana 山核桃和非洲山核桃的提取研究

The root bark of Tabernanthe iboga contains ibogaine as its predominant alkaloid and has been an important source of it. Ibogaine is used experimentally to interrupt drug addiction and allow therapeutic intervention, but is currently unaffordable to doctors in less economically developed countries. To meet this need, an extraction of alkaloids from T. iboga root bark was optimized and simplified to use only diluted vinegar and ammonia, and was successfully applied to related alkaloids from Voacanga africana bark also. The alkaloids were converted to their hydrochlorides and purified, and the minor alkaloids were recovered.
烟叶根皮以烟叶碱为主要生物碱，是烟叶碱的重要来源。伊博加因在实验中被用于中断药物成瘾并允许治疗干预，但目前经济欠发达国家的医生负担不起。为了满足这一需求，我们优化并简化了提取木耳根皮中生物碱的工艺，只使用稀释的醋和氨水，并成功地应用于木耳根皮中相关生物碱的提取。将生物碱转化为氢氯化物并提纯，回收少量生物碱。

Diastereoselective methylation of dimethyl (S)-malate 7, followed by two, three-step reductive de-hydroxylation procedures afforded dimethyl (R)-2-methylsuccinate 11 in 80.2% e.e. and 84.7% e.e., respectively. The latter compound was further transformed into the natural enantiomers of the ant venom alkaloids (R)-leptothoracine 1 and (R)-3-methyl-N-(2-phenylethyl)-pyrrolidine 2.
