IT-143A is a bacterial metabolite originally isolated fromStreptomycessp. IT-143.1It is active against the bacteriumM. luteus(MIC = 6.25 μg/ml) and the fungiA. fumigatusandT. rubrumin vitro(MICs = 12.5-25 μg/ml). 1.Urakawa, A., Sasaki, T., Yoshida, K., et al.IT-143-A and B, novel piericidin-group antibiotics produced by Streptomyces SpJ.

BOLD-100 (NKP-1339; IT-139) free base 是一款钌基抗癌药物。作为GRP78应激诱导上调的抑制剂,它破坏内质网(ER)的稳态,从而诱发ER应激和未折叠蛋白反应(UPR)。此外,BOLD-100 free base 干预了内质网应激反应、溶酶体动力学以及细胞自噬(autophagy)间的复杂交互作用。
Doxorubicin hydrochloride (Adriamycin) 属于蒽环类抗生素,是人类 DNA 拓扑异构酶 I II 抑制剂 (IC50=0.8 2.67 μM)。Doxorubicin hydrochloride 具有细胞毒性和抗肿瘤活性。Doxorubicin hydrochloride 可降低 AMPK 及其下游靶蛋白乙酰辅酶 A 羧化酶的磷酸化,还可诱导凋亡和自噬。
