iq 1

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.

IQ-1S is an inhibitor of NF-κB activating protein 1 (AP-1) with an IC50 of 1.8 μM. It exhibits high binding affinity to all three JNKs, with Kd values for JNK3, JNK2, and JNK1 being 87 nM, 360 nM, and 390 nM, respectively.

Camstatin TFA, a 25-residue fragment derived from the IQ motif of PEP-19, effectively binds to calmodulin and inhibits neuronal nitric oxide (NO) synthase, demonstrating its functional activity [1].

Me-IQ (Methyl-IQ) is a heterocyclic amine that exhibits both carcinogenic and mutagenic properties. It displays significantly higher mutagenic activity in liver microsomal preparations compared to those from the lungs in uninduced mice and rabbits [1] [2].
