The results showed that temperature rise would inhibit their esterification capacity, ethyl caproate-producing capability of raw zymin of 1# high-temperature monascus improved with the prolong of the esterification time when ethanol concentration was 4 %vol and caproic acid content was 4 mL, and when ethanol concentration and caproic acid content was within proper range, caproic acid content had more effects on the formation of ethyl caproate by raw zymin than ethanol concentration.

After esterification, the ethyl-2-chloro-3-phenylpropionate reacts with diethyl malonate under the catalysis of sodium ethylate, and we obtain the corresponding triethyl ester. The-benzylsuccinic acid is formed by the triethyl ester reacting with concentrate hydrochloric acid and taking place hydrolyzation and decarboxylation reaction at the same time. In order to avoid the formation of cinnamic acid, the sodium ethylate and diethyl malonate must be react sufficiently. The course has simple operation, inexpensive materials and better yield.

具体制备工艺为：首先以L-苯丙氨酸为原料采用重氮化方法得到-2-氯-3-苯基丙酸，再经酯化得到-2-氯-3-苯基丙酸乙酯后在乙醇钠催化作用下和丙二酸二乙酯缩合，发生SN2反应，得到相应的三乙酯，然后经水解和脱羧，得到-苄基丁二酸；在实验中乙醇钠要和丙二酸二乙酯充分反应，避免生成肉桂酸乙酯；该过程操作简单，原料便宜，产率较高，总收率可达到26.8%。

This is exactly opposite to the order of E465/E665 in HA and the order ofΔ~ K. It shows that the larger the extent of humification, the larger the effect for reducing the rate of Phoxim hydrolysis, because the extent of HA humification is closely related to the extent of benzene in HA and the amount of carbonyl, aryl, phenolic hydroxide.

因腐殖酸腐殖化程度与腐殖酸芳构化程度、羧基、羰基和酚羟基的含量等相关，因此用腐殖酸腐殖化程度反映腐殖酸对农药水解作用大小比仅用腐殖酸中有机碳含量等因素反映更为合理。

Restoration of ODC expression in the HL60-ODC cells resulted in rescue of rottlerin-induced apoptosis of HL60 cells. Simultaneously, phosphothreonine-ODC of rottlerin-treated HL60-ODC cells was highly elevated comparing with HL60-pcDNA3 cells. Taken together, we suggested that rottlerin, a PKCd inhibitor, might decrease phosphothreonine-ODC to reduce both protein stability and enzyme activity of ornithine decarbooxylase and finally resulted in cell apoptosis.
