md-2-in-1

MD2-IN-1 是骨髓分化蛋白 2 (MD2) 的抑制剂，对重组人 MD2 (rhMD2) 的 KD 为 189  μM。

Collismycin A is a bacterial metabolite originally isolated from Streptomyces that has diverse biological activities, including antibacterial, antiproliferative, and neuroprotective properties. It is active against a variety of bacteria (MICs = 6.25 and 100 μg ml) and fungi (MICs = 12.5-100 μg ml). It inhibits proliferation of A549 lung, HCT116 colon, and HeLa cervical cancer cells (IC50s = 0.3, 0.6, and 0.3 μM, respectively) and NIH373 fibroblasts (IC50 = 56.6 μM) but not MDA-MD-231 breast cancer cells (IC50 = >100 μM). Collismycin A forms a complex with Fe(II) and Fe(III) at a 2:1 ratio, and the addition of iron ions inhibits the antiproliferative effect of collismycin A on HeLa cells, an effect that does not occur with the addition of zinc, manganese, copper, or magnesium ions. Collismycin A (1 μM) prevents apoptosis in the brain region of zebrafish larvae by 44% in a model of neuronal cell death induced by all-trans retinoic acid .

NF-κB-IN-8 是一种化合物，其作用机制为竞争性抑制 LPS 与 MD-2 之间的相互作用。该化合物通过与 MD-2 结合，有效降低炎症因子的产生，并能够抑制 ALP 的酶活性。因此，NF-κB-IN-8 在急性肺损伤（ALI）等炎症性疾病的研究中具有潜在应用价值。

MD2-TLR4-IN-1 是一种骨髓分化蛋白 2 toll 样受体 4 (MD2-TLR4) 复合物抑制剂，能够抑制巨噬细胞 LPS 诱导的 TNF-α 和 IL-6 的表达，IC50值分别为 0.89 和 0.53 μM。
