X–Dipeptides (X=Z, Z(OMe), or Z(3Me)) have been catalytically synthesized by several microbial metalloproteinases. Among the enzymes used, Thermolysin showed the most remarkable ability in the coupling reactions of the esters or the amides of phenylalanine, leucine, isoleucine, and valine (and methionine in the case of the amide) with various X–amino acids. This method has been applied to the syntheses of ZPhePheOMe and ZPhePeOMe on a practical scale. Ammonium sulfate and sodium chloride had a marked effect on the condensed products, increasing the yield.
X-二肽(X=Z、Z(OMe)或Z(3Me))已通过几种微生物金属蛋白酶进行催化合成。在使用的酶中,耐热菌素在苯丙氨酸、亮氨酸、异亮氨酸、缬氨酸(以及在酰胺情况下为甲硫氨酸)的酯或酰胺与各种X-氨基酸的偶联反应中表现出最显著的能力。这一方法已被应用于实际规模的ZPhePheOMe和ZPhePheOMe合成中。硫酸铵和氯化钠对缩合产物有显著影响,能提高产量。
