Pharmacokinetics and tissue distribution of α-hederin sodium salt in rats / 中国中药杂志

To study the pharmacokinetics and tissue distribution characteristics of α-hederin sodium salt in rats. 100 mg•kg⁻¹ α-hederin sodium salt was given to the rats by intragastric administration, and LC-MS/MS method was used to determine its concentration at different time in plasma and tissues. Plasma and tissue samples were treated with methanol protein deposition method. Main pharmacokinetic parameters were as follows： tmax (0.97±1.23) h, Cmax (222.53±57.28) μg•L⁻¹, AUC0-t (1 262±788.9) h•μg•L⁻¹, T1/2 (17.94±9.50) h. α-hederin can be detected in heart, liver, spleen, lung, kidney, brain, muscle and adipose. The results showed that α-hederin sodium salt was absorbed fast and eliminated slowly in rats after oral administration. It was widely distributed in body tissues and livers kept the highest concentrations among various tissues at different time, so it can be speculated that α-hederin may have certain targeting property on livers.

The PKS/NRPS hetero-gene cluster of epothilones / 生物工程学报

Novel macrolides epothilones, produced by cellulolytic myxobacterium Sorangium cellulosum, have the activity to promote microtubule assembly, and are considered to be a potential successor to the famous antitumor drug taxol. The biosynthetic genes leading to the epothilones are clustered into a large operon. The multi-enzyme complex is a hetero-gene cluster of polyketide synthase (PKS) and non-ribosomal peptide synthetases (NRPS) and contains several functional modules, i.e. a loading module, one NRPS module, eight PKS modules, and a P450 epoxidase. The former ten modules biosynthesize desoxyepothilone (epothilones C and D), which is then epoxidized at C12 and C13 and converted into epothilones (epothilones A and B) by the P450 epoxidase. The NRPS module is responsible for the formation of the thiazole side chain from cysteine. The biosynthesis procedure of epothilones can be divided into 5 stages, i.e. formation of holo-ACP/PCP, chain initiation and thiazole ring formation, chain elongation, termination and epoxidation, and post-modification. The analysis of the gene cluster and the biosynthetic pathway reveals that novel epothilone analogs could not only be produced by chemical synthesis/modification, tranditional microbial technologies, but also can be genetically manipulated through combinatiorial biosynthesis approaches.
