Abstract

Official abstract text for this publication.

Described herein are compounds and compositions for the amelioration of arthritis or joint injuries by inducing mesenchymal stem cells into chondrocytes.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of (a) ameliorating arthritis or joint injury in a mammal, the method comprising administering to a joint of the mammal a composition comprising a therapeutically effective amount of a compound of Formula IIb, or a pharmaceutically acceptable salt, solvate, polymorph, prodrug, ester, metabolite, N-oxide, stereoisomer, or isomer thereof; or (b) inducing differentiation of mesenchymal stem cells into chondrocytes, the method comprising contacting mesenchymal stem cells with a sufficient amount of a compound of Formula IIb, or a pharmaceutically acceptable salt, solvate, polymorph, prodrug, ester, metabolite, N-oxide, stereoisomer, or isomer thereof: wherein each R 1 is independently halo, optionally substituted alkyl, optionally substituted alkoxy, optionally substituted aryloxy, CN, NO 2 , SR 4 , S(O)R 4 , SO 2 R 4 , NHR 5 , NR 4 R 5 , CO 2 H, or CO 2 R 4 ; n is 0, 1, 2, 3, or 4; B is NHC(O)R 2 ; R 2 is optionally substituted phenyl, optionally substituted heteroaryl, optionally substituted heterocyclyl, optionally substituted aralkyl, or optionally substituted alkyl; R 4 is optionally substituted phenyl, optionally substituted heteroaryl, optionally substituted heterocyclyl, optionally substituted aralkyl, or optionally substituted alkyl; R 5 is H, optionally substituted alkyl, C(O)R 4 , C(O)OR 4 , C(O)NR 4 R 4 , or SO 2 R 4 ; A is SO 2 NR a R b ; and each R a and R b is independently optionally substituted alkyl or together with the N to which they are attached make a ring. 2. The method of claim 1 , wherein each R a and R b is independently optionally substituted alkyl. 3. The method of claim 1 , wherein R a and R b together with the N to which they are attached make a ring. 4. The method of claim 1 , wherein R 2 is optionally substituted phenyl. 5. The method of claim 1 , wherein the phenyl of R 2 is monosubstituted or disubstituted. 6. The method of claim 5 , wherein substitution on the phenyl of R 2 is independently selected from F, Cl, CO 2 H, CN, OCH 3 , C(O)CH 3 , CF 3 , CH 3 , CH 2 OH, CH 2 CH 2 OH, and CH 2 CH 2 CH 2 OH. 7. The method of claim 1 , wherein the compound is: or a pharmaceutically acceptable salt, solvate, polymorph, prodrug, ester, metabolite, N-oxide, stereoisomer, or isomer thereof. 8. A method of (a) ameliorating arthritis or joint injury in a mammal, the method comprising administering to a joint of the mammal a composition comprising a therapeutically effective amount of a compound of Formula III, or a pharmaceutically acceptable salt, solvate, polymorph, prodrug, ester, metabolite, N-oxide, stereoisomer, or isomer thereof; or (b) inducing differentiation of mesenchymal stem cells into chondrocytes, the method comprising contacting mesenchymal stem cells with a sufficient amount of a compound of Formula III, or a pharmaceutically acceptable salt, solvate, polymorph, prodrug, ester, metabolite, N-oxide, stereoisomer, or isomer thereof: wherein each R 1 is independently halo, optionally substituted alkyl, optionally substituted alkoxy, optionally substituted aryloxy, CN, NO 2 , SR 4 , S(O)R 4 , SO 2 R 4 , NHR 5 , NR 4 R 5 , CO 2 H, or CO 2 R 4 ; n is 0, 1, 2, 3, or 4; X is O or NH and A is CH—CR 3 R 4 —C(O)R 2 ; or X is NR 6 and A is C(O) or CH 2 ; R 2 is optionally substituted aryl or optionally substituted heteroaryl; each R 3 and R 4 is independently H or optionally substituted alkyl; R 5 is H, optionally substituted alkyl, C(O)R 4 , C(O)OR 4 , C(O)NR 4 R 4 , or SO 2 R 4 ; and R 6 is optionally substituted phenyl; provided that if n is 0, A is CHCH 2 C(O)R 2 and X is O, then R 2 is not and if A is C(O) or CH 2 , then X is NR 6 and R 6 is not 9. The method of claim 8 , wherein R 2 is phenyl and the phenyl of R 2 is monosubstituted or disubstituted. 10. The method of claim 9 , wherein substitution on the phenyl is independently selected from F, Cl, CO 2 H, CN, OCH 3 , C(O)CH 3 , CF 3 , CH 3 , CH 2 OH, CH 2 CH 2 OH, and CH 2 CH 2 CH 2 OH. 11. The method of claim 8 , wherein n is 0 or 1. 12. The method of claim 11 , wherein R 1 is independently selected from Cl, F, CH 2 OH, CH 2 NH 2 , OCH 3 , OCF 3 , OCHF 2 , CN, NO 2 , CO 2 H, and CO 2 CH 3 . 13. The method of claim 8 , wherein the compound is or a pharmaceutically acceptable salt, solvate, polymorph, prodrug, ester, metabolite, N-oxide, stereoisomer, or isomer thereof.
