Ghose filter\nReceptor binding, cellular uptake and bioavailability of drug molecules is strongly influenced by molecular lipophilicity and molar refractivity. Both of them signify hydrophobic and dispersive (van der Waals) interactions (Ghose \u0026 Crippen, 1987) of a drug molecule and are employed in 3D-QSAR studies to evaluate the drug-like character of molecules under study (Viswanadhan et al., 1990, 1991). The following are the qualifying parameters for a putative drug candidate as per Ghose filter:clogP range between -0.4 and 5.6, with an average value of 2.52;\nMW range between 160 and 480, with an average value of 357;\nMolar refractivity range between 40 and 130, with an average value of 97;\nTotal number of atoms between 20 and 70, with an average value of 48.\nThe above parameters should be kept in mind for testing hypothetically proposed compounds before any in vitro and in vivo experimentation (Ghose, 1987; Ghose et al., 1999)."}
