Search for new antiphytovirucides

The lead compound of substituted 2-(4′-hydroxyphenyl)benzimidazoles were modified by phosphorylation sulfonation and carboxymethylation. The benzimidazoloamidophosphate (6) (7) have better activity against tobacco mosaic virus (TMV). The benzimidazolophenoxyacetic acid, phenoxysulfonic acid containing trifluoromethyl, and nitro group have 77%≈85% efficiency for wheat rust disease.

Cloning and expression of the vp39 gene ofBombyx mori nuclear polyhedrosis virus inE. coli

The nuclear capsid protein gene (vp39) ofBombyx mori nuclear polyhedrosis virus (BmNPV) was amplified successfully by PCR technique and inserted into pGEM 3zf(+). The 5′ and 3′ terminal area of the amplified vp39 gene were sequenced with silver-staining dideoxy method. Bmvp39 gene was sub-cloned into the expression vector pRSET-A, and transformed intoE. coli BL21. This gene was highly expressed by IPTG induction. SDS-PAGE analysis showed that the expressed protein is about 38 kd, and the expressed amount reached maxium in 4 h with IPTG induction.

1,3—二氯—2—丙醇氧化反应的研究

对１,３－二氯－２－丙醇的氧化反应进行了系统的研究,将８４％的硫酸溶液慢慢滴加到包含有１,３－二氯－２丙醇和重铬酸钠水溶液的反应容器中去,将体系保持在２４℃～２６℃拦反应６ｈ,反应完成后,过滤回收１,３－二氯丙酮粗品,粗品用冰水洗涤,然后通过蒸馏经可获得８０．４％的收率的１,３－二氯丙酮,这是一种合成１,３－二氯丙酮较好的工艺,这种工艺与同类文献介绍的方法比较目标产物收率提高１０％,而反应时间缩短
