Cytochalasin H ((16-Benzyl-5,12-dihydroxy-5,7,14-trimethyl-13-methylidene-18-oxo-17-azatricyclo[9.7.0.01,15]octadeca-3,9-dien-2-yl) acetate) 是肌动蛋白掺入细丝的有效抑制剂。
OSK-1 is a potent potassium channel blocker belonging to the α-KTx3 toxins. It exhibits IC50 values of 0.6 nM, 5.4 nM, and 0.014 nM for Kv1.1, Kv1.2, and Kv1.3 channels, respectively. Additionally, OSK-1 acts as a moderate blocker of the calcium-activated KCa3.1 channel, with an IC50 of 225 nM. Consequently, OSK-1 finds application as an immunosuppressive drug.
UNC-CA359 is a highly potent inhibitor of the epidermal growth factor receptor (EGFR), demonstrating an IC50 value of 18 nM. With strong anti-tumor activity, UNC-CA359 holds significant potential for chordoma research [1].
