Concanamycin A (Folimycin) 是一种多聚环内酯类抗生素,是选择性空泡状 H+-ATP 酶 (V-ATPase) 和溶酶体酸化抑制剂,可用于研究炎症。Concanamycin A 可增强细胞毒性 T 淋巴细胞对受感染原代细胞的免疫清除,抑制来自 HIV 和猿猴免疫缺陷病毒不同分支的 Nef 等位基因,可用于研究HIV 感染。
SCL-1 是一种口服有效的抗PD-1/PD-L1抑制剂,能够抑制PD-1/PD-L1结合,并增加 T 细胞、B 细胞和自然杀伤细胞的数量。其通过在肿瘤内诱导效应 T 细胞及上调长链非编码 RNA 作为新抗原的表达而激活细胞毒性 T 淋巴细胞,对肿瘤生长有强大抑制作用。SCL-1 可用于癌症研究,尤其是在三阴性乳腺癌方面。
DMI-9523 is nuclear factor NF-κB activation inhibitor. Antigen-stimulated human T lymphocytes produce significantly lower quantities of interferon-gamma and tumor necrosis factor-alpha after stimulation in vitro in the presence of DA-DKP. DA-DKP can modul
O-11 is an analog of the fully saturated, 14-carbon fatty acid myristic acid, in which the methylene group at position 11 is replaced with oxygen. It is highly effective and selective at killingTrypanosoma brucei, the protozoan parasite responsible for African sleeping sickness, exhibiting an LD50of less than 1 μM in a cell culture assay.1,2The toxic effects of O-11 appear to be caused by its ability to inhibit the incorporation of a single myristate into the GPI anchor of the variant surface glycoprotein (VSG), a protein critical for evading the host immune response.1O-11 exhibits essentially no anti-fungal activity when assayed usingC. neoformans, but does have a minor inhibitory effect on HIV-1 replication in T-lymphocytes.3

Padanamide A is a bacterial metabolite originally isolated from a marine Streptomyces species. It is active against five strains of P. falciparum (EC50s = 160-340 nM), is not cytotoxic to HEK293 or HepG2 human cell lines, but is cytotoxic to Jurkat T lymphocytes with an IC50 value of approximately 60 μg/ml.
