Identification of 5-hydroxytryptamine1A receptor agents using a composite pharmacophore analysis and chemical database screening
      
A composite pharmacophore analysis and computer-assisted chemical database screening were used to identify a previously unrecognized class of 5-hydroxytryptamine1A (5-HT1A) receptor active agents.
      
These data suggest that a composite pharmacophore analysis and computer-assisted chemical database screening can be an effective technique for the identification of previously unrecognized receptor active agents.
      
This regularity is discussed with reference to statistical treatment of chemical database as a means to screen identification hypotheses.

Attempt is made to improve the UNIQUAC model because there are limitations when applied to some systems containing water and alcohol. Incorporating the chemistry data base with the model to make some of the pure compound parameters be adjustable and to process them by using the experimental data of vapor liquid equillibrium stored in the data base,much better results can be obtained.

本文在学习UNIQUAC模型基础上探讨了它的局限性。与化学数据库联用,将模型中的纯组份性质参数作为由实测相平衡数据确定的可调参数处理,解决了不同温度下参数不统一和对不同体系模型形式不统一的问题,计算精度亦显著提高,为在线应用化学数据库提供了一种可能性。

We have modified and simplified Latimer's method for estimation of the standard entropies of binary oxides, and extended to high temperature region successfully. The values of the entropies of 20 compounds at different temperatures have been predicted. The root mean square error of 18 compounds of them is less than 5 cal/mol·K which corresponds to the experimental error of the standard entropy of some binary oxides.

标准熵的估算方法以W.M.Latimer法最为著名。本文对此作了若干修正,并成功地将它推广应用到高温情况。作为试验,本文预报了二十个复氧化物在不同温度下的熵值,其中十八个化合物的均方根偏差小于5cal/mol·K,即与若干复氧化物标准熵的实验误差相当。因此本方法可以装入“无机热化学数据库”。使它增加预报复氧化物高温熵的功能。
