Summary:PROBLEM TO BE SOLVED: To find methods for simply synthesizing fused compounds which contain a pyridopyrimidine skeleton and a steroid skeleton and have a wide application range and to provide useful compounds which can be obtained by the methods. SOLUTION: The useful compounds are 5'-deaza-17β-hydroxy-2'-phenyl-5α-androst-2-eno[2,3-g]pteridin-4'(8,H)-ones, 5'-deaza-17β-hydroxy-5α-androst-2-eno[2,3-g]pteridin-2',4'(3'H,8'H)-diones, and 5'-deaza-17β-hydroxyandrost-2,4-dieno[2,3-g]pteridin-2',4'(3'H,8'H)-diones. Their manufacturing methods are provided. COPYRIGHT: (C)2005,JPO&NCIPI
