4-Phenylamino-6,7-dimethoxyquinazoline

Description

WHI-P258 is a quinazoline compound that modeling studies suggested would bind to the active site of JAK3 with an estimated K_i value of 72 μM. However, it is inactive at JAK3 (IC₅₀ = >300 μM) and has been used as a negative control for structurally similar compounds that inhibit platelet aggregation and herpes simplex virus 1 (HSV-1) replication.

Uses

4-Phenylamino-6,7-dimethoxyquinazoline is a specific inhibitors of Janus kinase 3 (JAK3).
