Analogues of methenmadinone acetate include methenmadinone caproate (MMC), which was studied in combination with estradiol valerate as a combined injectable contraceptive (tentative brand name Lutofollin);[15][16][17] chlormethenmadinone acetate (chlorsuperlutin; SCH-12600; 6-chloro-MMA),[18] which has been used in combination with mestranol in birth control pills (brand names Biogest, Sterolibrin, Antigest B)[19][20] and in veterinary medicine (brand name Agelin);[21] bromethenmadinone acetate (bromsuperlutin; 6-bromo-MMA), which was assessed but was never marketed;[20][22] and melengestrol acetate (methylsuperlutin; 6-methyl-MMA), which is used in veterinary medicine.[6]
