of intermolecular hydrogen bonds in the solid state, which, in our opinion, can have a significant impact on the interaction of the new drug with biological targets. Thus, by comparing the X-ray structural analysis data, the probability of the influence of the nature of the counterion on the biological effect of the drug was demonstrated.
先前描述的L-精氨酸5-甲基-6-硝基-7-氧代-4,7-二氢-1,2,4-三唑并[1,5- a ]嘧啶一水合物和哌啶5-甲基-6-硝基- 7-氧代4,7-二氢-1,2,4-三唑[1,5- a以前没有描述过的]嘧啶胺被合成为有前途的抗病毒药物。对这两种化合物的晶体结构进行了详细的比较。结果表明,用哌啶一取代L-精氨酸阳离子会导致固态分子间氢键系统的严重重组,我们认为,这可能会对新药的相互作用产生重大影响具有生物目标。因此,通过比较X射线结构分析数据,证明了抗衡离子的性质对药物的生物学作用的影响的可能性。
