Molecular Shape Descriptors. 3. Steric Mapping of Biological Receptor
نویسنده
چکیده
The paper presents and illustrates and improved version of the SIBIS algorithm. SIBIS is a self-consistent type algorithm which is well suited to delineate the main steric features of biological receptor, identify missing relevant atoms and/or presence of superfluous atoms in the molecules studied, and to provide an approximate estimate for the receptor bulk tolerance. SIBIS calculations for a set of substituted benzoates in the anti-p-(p'-azophenylazo)benzoate system yield an excellent QSAR (n = 18, r = 0.989, 5 = 0.192, F= 20S.16) which is further supported b> the information correlation coefficients, R (/?'s express quantitatively the pairwise degree of the molecular shape relatedness); the optimal receptor steric map is in agreement with experimental evidences.

Each molecule has its own specialty, structure and function and when these molecules are combined together they form a compound. Structure and function of a molecule are related to each other and QSARs (Quantitative Structure– Activity relationships) are based on the criteria that the structure of a molecule must contain the features responsible for its physical, chemical, and biological proper...

متن کاملTopological Substituent Descriptors
Motivation. Substituted 1,3,5-triazines are known as useful herbicidal substances. In view of reducing the cost of biological screening, computational methods are carried out for evaluating the biological activity of organic compounds. Often a class of bioactives differ only in the substituent attached to a basic skeleton. In such cases substituent descriptors will give the same prospecting res...
