The synthesis of several new oxorhenium(V) complexes containing the ‘3 + 1’ mixed-ligand donor set, ReO(SXS)(SR) (where X = S, O, N(R′); R = alkyl, aryl, heterocylce; R′ = H, alkyl, aryl), is described. The X-ray structure for four of these complexes ReO(SN(Ph)S)(SPh) ( 6 ), ReO(SN(CH 2 CH 2 NMe 2 )S)(SPhOMe- p ) ( 10 ), ReO(SOS)(SPh) ( 29 ) and ReO(SOS)(SPhNO 2 - p ) ( 30 ) was determined. The inhibitory
几种新的含'3 +1'混合配体供体集合的氧杂S(V)配合物的合成(ReX(SXS)(SR)(其中X = S,O,N(R'); R =烷基,芳基,描述了杂环; R'= H,烷基,芳基)。这些复合物中的四个ReO(SN(Ph)S)(SPh)(6),ReO(SN(CH 2 CH 2 NMe 2)S)(SPhOMe- p)(10),ReO(SOS)的X射线结构)(SPh)(29)和ReO(SOS)(SPhNO 2-p)(30)被确定。在体外评估了本文报道的所有氧化or(V)复合物对半胱氨酸蛋白酶组织蛋白酶B和K的抑制活性。化合物25 ReO(SSS)(S-4py)·HCl是针对组织蛋白酶B的最佳抑制剂,IC 50为10 nM。几种配合物表现出对组织蛋白酶B超过K的特异性,这表明oxorhenium(V)配合物可以设计成对酶具有特异性。
