Imatinib is a multi-target inhibitor of v-Abl, c-Kit, and PDGFR (IC50: 0.6 μM, 0.1 μM, and 0.1 μM, respectively). Imatinib is used to treat chronic myelogenous leukemia (CML), gastrointestinal stromal tumors (GISTs), and a number of other malignancies.
Lipid-derived lipoxins are produced at the site of vascular and mucosal inflammation where they down-regulate polymorphonuclear leukocyte recruitment and function. 15(R)-Lipoxin A4 (15(R)-LXA4) is derived from the aspirin-triggered formation of 15(R)-HETE from arachidonic acid. [1] [2] 15(R)-LXA4 inhibits LTB4-induced chemotaxis, adherence, and transmigration of neutrophils with twice the potency of LXA4 demonstrating activity in the nM range.[2] [3] The anti-inflammatory effects of aspirin may be ascribed in part to the ability of 15(R)-LXA4 to regulate leukocyte function.[4] 15(R)-LXA4 is reported to promote resolution of inflammation in LPS-treated stromal cells derived from intermediate-stage diseased supraspinatus tendons as evidenced by increased expression of the STAT-6 pathway target genes, ALOX15 and CD206.[5]
KLD-12, a 12-residue self-assembling peptide, displays properties that promote chondrogenic differentiation of bone marrow stromal cells (BMSCs). Moreover, KLD-12 hydrogel can effectively fill full-thickness osteochondral defects in their original location, leading to improved cartilage repair.
