calf-thymus DNA (CT DNA) and BSA (bovine serum albumin) was studied by means of CD, UV and fluorometric techniques. According to the spectroscopic data, an interaction of the metal complexes with CT DNA was confirmed. A significant increase in the melting point of CT DNA in the presence of the metal complexes ΔTm = 10.0 °C (for 2b), 12.5 °C (for 5b)} indicates a strong stabilization of the DNA helix. According

constants (Kbin) of Pd(II) complexes with BSA are in the range 0.83–4.12 × 105 L M−1. The molecular docking studies show the minor groove binding behavior of tetrazole-containing palladium(II) and platinum(II) complexes to DNA (ΔGbinding. −5.56 − −6.12 kcal/mol) and effective binding to BSA via the favored binding site Trp213 (ΔGbinding −7.2 − −7.56 kcal/mol). The complex trans-[PtCl2(2-tert-butyl-tetrazol-5-ylacetic
摘要具有四唑-1-基和四唑-5-基乙酸的酯(反式-[PdCL2L2]和反-[PtCL2L2])的两个系列的钯(II)和铂(II)配合物,L = 5-甲基-1H-四唑-1-基乙酸及其乙酯,丁酯,异丁酯(1-5);合成了2-R-2H-四唑-5-基乙酸及其乙酯,R = tBu,CH2CH2OH(6-10)},并与小牛胸腺DNA(CT DNA)和牛血清白蛋白(BSA)结合。通过实验(CD,UV,粘度测定,荧光测定和电泳技术)和理论方法进行研究。根据分光光度数据,观察到金属络合物与CT DNA的相互作用。在存在金属配合物的情况下,CT DNA的熔点显着增加(ΔTm= 8–13°C),表明DNA螺旋结构具有很强的稳定性。电泳研究表明金属络合物与pBR322质粒DNA相互作用并改变其迁移率的能力。根据荧光猝灭技术的数据,与BSA的Pd(II)配合物的常数(Kbin)结合范围为0.83–4.12×105 L
A Reagent, Ethyl 2-(2-tert-Butyl-2H-tetrazol-5-yl)-3-(dimethylamino)acrylate (DMTE), for Facile Synthesis of 2,3-(Ring Fused)-5-(5-teratzolyl)-4H-pyrimidin-4-one Derivatives.
A method for synthesizing 2, 3-(ring fused)-5-(5-tetrazolyl)-4H-pyrimidin-4-one derivative from ethyl 2-(2-tert-butyl-2H-tetrazol-5-yl)-3-(dimethylamino)acrylate (DMTE) (4a) and amino-heterocycles is described. The structure of DMTE, which was prepared from ethyl (2-tert-butyl-2H-tetrazol-5-yl)acetate (3a) with dimethylformamide diethylacetal, was determined by X-ray analysis to be Z form. The reaction of 2-amino-5-methyloxazole (6) with DMTE in acetic acid gave the oxazolo[3, 2-a]pyrimidine derivative (8), heating of which in concentrated sulfuric acid afforded the desired tetrazole derivative (20). Pyrimido[2, 1-b]benzothiazole (21), pyrazolo[1, 5-a]pyrimidine (22 and 23) and [1, 2, 4]triazolo[1, 5-a]pyrimidine (24) derivatives were prepared in a similar manner.
