The invention concerns novel 2-[4-(4-chlorophenyl)-benzyloxy]acetic acids of the formula:
in which RI is hydrogen or (1-4C)alkyl, R2 is phenyl optionally bearing a halogeno substituent, and R3 is hydrogen or (1-4C)alkyl, and when R3 is hydrogen pharmaceutically acceptable base-addition salts thereof; and processes for their manufacture.
The compounds possess useful anti-arthritic properties coupled with desirable pharmacokinetic properties and the minimum of adverse properties, and the invention also concerns pharmaceutical compositions of such compounds for use in the treatment of arthritic joint diseases. A typical compound of the invention is 2-[4-(4-chlorophenyl)benzyloxy]propionic acid.
本发明涉及式如下的新型 2-[4-(4-
氯苯基)-苄氧基]
乙酸:
其中RI是氢或(1-4C)烷基,R2是可选带有卤代基的苯基,R3是氢或(1-4C)烷基,当R3是氢时是其药学上可接受的碱加成盐;以及它们的制造工艺。
这些化合物具有有用的抗关节炎特性,同时具有理想的药代动力学特性和最小的不良特性,本发明还涉及用于治疗关节炎性关节疾病的此类化合物的药物组合物。本发明的一种典型化合物是 2-[4-(4-
氯苯基)苄氧基]
丙酸。
