Abstract:
A method of contraception, which comprises administering to a female of child bearing age for 28 consecutive days:a) a first phase of from 14 to 24 daily dosage units of a progestational agent equal in progestational activity to about 35 to about 100 &mgr;g levonorgestrel; b) a second phase of from 1 to 11 daily dosage units, at a daily dosage of from about 2 to 50 mg, of an antiprogestin compound of Formula I: â€ƒwherein: R1 and R2 are independent substituents selected from the group consisting of H, C1 to C6 alkyl, substituted C1 to C6 alkyl, C2 to C6 alkenyl, substituted C2 to C6 alkenyl, C2 to C6 alkynyl, substituted C2 to C6 alkynyl, C3 to C8 cycloalkyl, substituted C3 to C8 cycloalkyl, aryl, substituted aryl, heterocyclic, substituted heterocyclic, CORA, and NRBCORA; or R1 and R2 are fused to form: (i) a carbon-based saturated 3 to 8 membered spirocyclic ring, (ii) a carbon-based 3 to 8 membered spirocyclic ring having one or more carbonâ€”carbon double bonds; or (iii) a 3 to 8 membered spirocyclic, heterocyclic ring having in its backbone one to three heteroatoms selected from the group consisting of O, S and N; the spirocyclic rings of (i), (ii), and (iii) being optionally substituted by from 1 to 4 groups selected from the group consisting of fluorine, C1 to C6 alkyl, C1 to C6 alkoxy, C1 to C6 thioalkyl, CF3, OH, CN, NH2, NH(C1 to C6 alkyl), and N(C1 to C6 alkyl)2; RA is H, C1 to C3 alkyl, substituted C1 to C3 alkyl, aryl, substituted aryl, C1 to C3 alkoxy, substituted C1 to C3 alkoxy, C1 to C3 aminoalkyl, or substituted C1 to C3 aminoalkyl; RB is H, C1 to C3 alkyl, or substituted C1 to C3 alkyl; R3 is H, OH, NH2, C1 to C6 alkyl, substituted C1 to C6 alkyl, C3 to C6 alkenyl, substituted C3 to C6 alkenyl, alkynyl, substituted alkynyl, or CORC; RC is H, C1 to C3 alkyl, substituted C1 to C3 alkyl, aryl, substituted aryl, C1 to C3 alkoxy, substituted C1 to C3 alkoxy, C1 to C3 aminoalkyl, or substituted C1 to C3 aminoalkyl, R4 is H, halogen, CN, NO2, C1 to C6 alkyl, substituted C1 to C6 alkyl, alkynyl, substituted alkynyl, C1 to C6 alkoxy, substituted C1 to C6 alkoxy, amino, C1 to C6 aminoalkyl, or substituted C1 to C6 aminoalkyl; R5 is (iv) or (v): (iv) a substituted benzene ring of the structure: X is selected from the group consisting of halogen, CN, C1 to C3 alkyl, substituted C1 to C3 alkyl, alkynyl, substituted alkynyl, C1 to C3 alkoxy, substituted C1 to C3 alkoxy, C1 to C3 thioalkoxy, substituted C1 to C3 thioalkoxy, amino, C1 to C3 aminoalkyl, substituted C1 to C3 aminoalkyl, NO2, C1 to C3 perfluoroalkyl, 5 or 6 membered heterocyclic ring having in its backbone 1 to 3 heteroatoms, CORD, OCORD, and NRECORD; RD is H, C1 to C3 alkyl, substituted C1 to C3 alkyl, aryl, substituted aryl, C1 to C3 alkoxy, substituted C1 to C3 alkoxy, C1 to C3 aminoalkyl, or substituted C1 to C3 aminoalkyl; RE is H, C1 to C3 alkyl, or substituted C1 to C3 alkyl; Y and Z are independent substituents selected from the group consisting of H, halogen, CN, NO2, amino, aminoalkyl, C1 to C3 alkoxy, C1 to C3 alkyl, and C1 to C3 thioalkoxy; or (v) a five or six membered ring having in its backbone 1, 2, or 3 heteroatoms selected from the group consisting of O, S, SO, SO2 and NR6 and having one or two independent substituents selected from the group consisting of H, halogen, CN, NO2, amino, C1 to C3 alkyl, C1 to C3 alkoxy, C1 to C3 aminoalkyl, CORF, and NRGCORF; RF is H, C1 to C3 alkyl, substituted C1 to C3 alkyl, aryl, C1 to C3 alkoxy, substituted C1 to C3 alkoxy, C1 to C3 aminoalkyl, or substituted C1 to C3 aminoalkyl; RG is H, C1 to C3 alkyl, or substituted C1 to C3 alkyl; R6 is H or C1 to C3 alkyl; G1 is NR7 or CR7R8; G2 is CO or CR7R8; provided that G1 and G2 cannot both be CR7R8; R7 and R8 are independently selected from the group consisting of H, alkyl, substituted alkyl, aryl, and heterocyclic; or pharmaceutically acceptable salt thereof; and c) optionally, a third phase of daily dosage units of an orally and pharmaceutically acceptable placebo for the remaining days of the 28 consecutive days in which no antiprogestin, progestin or estrogen is administered; wherein the total daily dosage units of the first, second and third phases equals 28.
