hydroxamic acid (SAHA), with hydrated metal salts of Fe(III), Cu(II), Ni(II) and Zn(II) yielded a tris-hydroxamato complex in the case of Fe(III) and bis-hydroxamato complexes in the case of Cu(II), Ni(II) and Zn(II) both in the solid state and in solution. Reaction of the secondary hydroxamic acid, N-Me-SAHA, also yielded a tris-hydroxamato complex in the case of Fe(III) and bis-hydroxamato complexes in the
强效的基于异羟肟酸酯的组蛋白脱乙酰基酶(HDAC)抑制剂,亚磺酰苯胺异羟肟酸(SAHA)与Fe(III),Cu(II),Ni(II)和Zn(II)的水合金属盐的反应产生了tris-hydroxamato在固态和溶液态下,Fe(III)为双金属配合物,Cu(II),Ni(II)和Zn(II)为双氢肟基配合物。仲异羟肟酸N -Me-SAHA的反应在Fe(III)的情况下也产生了tris-hydroxamato配合物,在Cu(II),Ni(II)和Zn(II )。这些金属络合物具有以O, O'-双齿形式配位的异羟肟酸酯部分。在DMSO / H 2中与SAHA和N -Me-SAHA形成的金属配合物的稳定性常数描述了70/30%(v / v)的混合物。还报道了SAHA的新型晶体结构以及N -Me-SAHA的新型合成。
