This invention relates to a method of treatment for osteoarthritis involving inhibitors of aggrecanase that demonstrate IC
50
s of less than 20 nM and demonstrate differential potency against matrix metalloproteinases (MMPs) and a disintegrin and metalloproteinases (ADAMs or reprolysins). This invention also relates to compounds, methods of treatment and composition of Formula I:
or a therapeutically acceptable salt thereof, wherein X is carbon or nitrogen;
R
1
and R
2
are independently selected from the group consisting of hydrogen, hydroxy, and methyl, wherein at least one of R
1
and R
2
is methyl;
R
3
and R
4
are independently selected from the group consisting of hydrogen, hydroxy, and methyl, or R
3
and R
4
may be taken together to form a carbonyl group; and
R
5
and R
6
are independent substituents in the ortho, meta, or para positions and are independently selected from the group consisting of hydrogen, halogen, cyano, methyl, and ethyl; with the provisos:
when X is carbon, then R
7
and R
8
are both hydrogen and at least one of R
1
, R
2
, R
3
, and R
4
is hydroxy;
when X is carbon and R
5
is para-halo, then at least one of R
6
, R
3
, and R
4
is not hydrogen;
when X is nitrogen, then R
8
is not present and R
7
is hydrogen or a group of the formula:
wherein, Y is —CH
2
—NH
2
or —NH—CH
3
; and
when X is nitrogen and R
7
is H, then R
3
and R
4
are taken together to form a carbonyl group.
这项发明涉及一种治疗骨关节炎的方法,涉及抑制aggrecanase的抑制剂,其IC50小于20 nM,并且对基质金属蛋白酶(MMPs)和脱粒蛋白酶(ADAMs或reprolysins)表现出差异的效力。这项发明还涉及化合物、治疗方法和Formula I的组成:
或其治疗上可接受的盐,其中X为碳或氮;
R1和R2分别选自氢、羟基和甲基组成的群,其中至少一个为甲基;
R3和R4分别选自氢、羟基和甲基组成的群,或R3和R4可一起形成一个羰基;以及
R5和R6是正交位、间位或对位的独立取代基,分别选自氢、卤素、氰基、甲基和乙基;附加条件:
当X为碳时,R7和R8都是氢,且至少一个R1、R2、R3和R4为羟基;
当X为碳且R5为对位卤素时,至少一个R6、R3和R4不是氢;
当X为氮时,R8不存在且R7为氢或一个公式的基团:
其中,Y为—CH2—NH2或—NH—CH3;以及
当X为氮且R7为H时,R3和R4一起形成一个羰基。
