ABSTRACT

 

Adhikari K, Lahiri T, Mishra H, Kalpana Singh, Kumar CN., Model to recognize drug from non-drug like  molecules, Onl J Bioinfo., 26 (1) :37-46, 2025. A  model to identify drug like characteristics of any small molecule from any database is described. Algorithms were used extract 15 of 785 sets of features found to be significant for discrimination between drug and non-drug like molecules. These features were fed into a neural network classifier and weights and biases optimized through a Neuro-GA module. Drug molecules (409) were extracted from chEMBL and Non-drug (735) from ZINC database SMILES representation. For selection of best features of 785 with filter 23% using P > 1 while 73.76% features with P < 0.05, yielded 580 with strong discriminating power. For classification of 600 molecules into drug and non-drug like with 450 training 150 test sets. Accuracy was 88% for training and test data 86%. With Neuro-GA, accuracy was enhanced to 91%.
