p38 Kinase inhibitors for the treatment of arthritis and osteoporosis: thienyl, furyl, and pyrrolyl ureas
摘要:
Inhibitors of the MAP kinase p38 are potentially useful for the treatment for osteoporosis, arthritis, and other inflammatory diseases. A series of thienyl, furyl, and pyrrolyl ureas has been identified as potent p38 inhibitors, displaying in vitro activity in the nanomolar range. (C) 2000 Elsevier Science Ltd. All rights reserved.

A direct cyanation of terminal alkynes for the synthesis of propionitrile derivatives, with the aid of silver salt using water additive, has been achieved. The cyano source used is N-isocyanoiminotriphenylphosphorane, which is nontoxic, safe, and easy to handle. This protocol is characterized by its operational simplicity, high efficiency with excellent yields, broad substrate scope, and greater functional group tolerance.
