Heparin calcium (MW 15000-19000) 是一款高效的抗凝剂,能通过与抗凝血酶 III (ATIII) 形成可逆的复合物——肝素-抗凝血酶 III 复合物。该复合物进一步与凝血酶以及其他活化的凝血因子如IX、X、XI 和 XII 结合,以不可逆的方式使它们失活,从而有效防止纤维蛋白原转变为纤维蛋白。
MW-150 hydrochloride (MW01-18-150SRM hydrochloride) is a potent and selective inhibitor of p38α MAPK, with a Ki value of 101 nM. It exhibits excellent CNS penetration and oral bioavailability. MW-150 hydrochloride (MW01-18-150SRM hydrochloride) effectively suppresses the phosphorylation of MK2, a substrate of endogenous p38α MAPK, in activated glial cells.
13C15-Nivalenol is intended for use as an internal standard for the quantification of nivalenol by GC- or LC-MS. Nivalenol is a trichothecene mycotoxin that has been found inFusarium.1It is lethal to mice (LD50= 6.9 mg kg).2Nivalenol (5, 10, and 15 mg kg) also induces thymic, splenic, and Peyer's patch cell apoptosis in mice.3 1.Yang, Z., Concannon, J., Ng, K.S., et al.Tetrandrine identified in a small molecule screen to activate mesenchymal stem cells for enhanced immunomodulationSci.
