Patent ID: 8853437

Claim:
A compound selected from the group consisting of: or a pharmaceutically acceptable salt thereof, wherein, P 1 and P 2 are each independently, a hydrogen atom, alkyl, a hydroxyl group or a substituted hydroxyl group, benzyl ether, trityl ether, alkyl ether, tetrahydropyranyl ether, trialkylsilyl ether, glycol ether, or allyl ether, when indicates a single bond, P 1 , P 2 , R 1 and R 2 are not present, when indicates a double bond, and when is a single bond, R 1 and R 2 are each independently a hydrogen atom, a halogen atom, a substituted or unsubstituted branched or non-branched alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted branched or non-branched alkylaryl group, or a combination thereof; X is —C(O)OR 3 , —C(O)NR 4 R 5 , —C(O)H, —C(NH)NR 4 R 5 , —C(S)H, —C(S)OR 3 , —C(S)NR 4 R 5 , or —CN; R 3 is hydrogen, benzyl ether, trityl ether, alkyl ether, tetrahydropyranyl ether, trialkylsilyl ether, glycol ether, allyl ether, substituted or unsubstituted alkyl, substituted or unsubstituted alkenyl, substituted or unsubstituted alkynyl, substituted or unsubstituted aryl, substituted or unsubstituted heteroaryl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted cycloalkenyl, substituted or unsubstituted heterocycle or a group of the formula: —NR a R b , wherein R a and R b are each independently hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted alkenyl, substituted or unsubstituted alkynyl, substituted or unsubstituted aryl, substituted or unsubstituted heteroaryl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted cycloalkenyl, substituted or unsubstituted heterocycle, or R a and R b are optionally taken together with an adjacent nitrogen atom to form a substituted or unsubstituted nitrogen-comprising heterocyclic ring; R 4 and R 5 are each independently hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted alkenyl, substituted or unsubstituted alkynyl, substituted or unsubstituted aryl, substituted or unsubstituted heteroaryl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted cycloalkenyl, or substituted or unsubstituted heterocycle, or R 4 and R 5 are optionally taken together with an adjacent nitrogen atom to form a substituted or unsubstituted nitrogen-comprising heterocyclic ring; and double bond configuration of the compound can be any of cis or trans.
