iq1

IQ 1 has multiple roles, such as maintaining the multifunctionality of mouse ESCs, decreasing Wnt-stimulated phosphorylation, blocking PP2A Nkd interactions, and so on.

IQ-1S free acid (IQ-1S) is an effective and specific c-Jun N-Terminal Kinase Inhibitor. IQ-1S inhibits murine delayed-type hypersensitivity. IQ-1S can reduce inflammation and cartilage loss associated with CIA and can serve as a small-molecule modulator for mechanistic studies of JNK function in rheumatoid arthritis. IQ-1S is highly specific for JNK and that its neutral form is the most abundant species at physiologic pH.

SIQ17, an EGFR inhibitor, blocks the ATP-binding site with an IC50 of 0.62 nM, demonstrating more effective EGFR-TK inhibitory activity than the known inhibitor Erlotinib (IC50 of ∼20 nM). SIQ17 is applicable in cancer research [1].
