Oral dosing is considered as the most appropriate way for administering drugs. One of the widely used virtual screeningmethod for compounds intending to be orally active is the RO5 [25], as this set of rules were derived from property analysis profiles of compounds that have survived preclinical stages and Phase I safety evaluations. Most common drug like properties areattributed to those compounds that qualifies to possess molecular weight <500, clogP (octanol–water partition coefficient) <5, HDO (hydrogen-bond donor) >5, HAC (sum of the number of nitrogen and oxygen atoms or hydrogen bond acceptors) >10. Also, the Total Polar Surface Area (TPSA) has been found to be directly correlatedto HDO and HAC [38,39]. Out of the four hundred and sixty four steroids, only twenty five of them satisfied the Lipinski drug filters so as to project their oral bioavailability factor which becomes evident from Table S8 as all of them have molecular weight <500, rotatable bonds were <10, hydrogen bond donors and acceptors were <12 and TPSA values being <140 ÅA 2
