FSL-1 TFA, a bacterial-derived toll-like receptor 2 6 (TLR2 6) agonist, enhances resistance to experimental HSV-2 infection[1]. FSL-1 TFA induces MMP-9 production through TLR2 and NF-κB AP-1 signaling pathways in monocytic THP-1 cells[2]. FSL-1 significantly reduces HSV-2 replication in human vaginal epithelial cells (EC)[1].FSL-1 induces significant resistance to experimental genital HSV-2 infection through elaboration of a specific cytokine response profile[1].FSL-1 (50 ng mL, 24 hours) induces MMP-9 expression at both mRNA and protein levels in human monocytic THP-1 cells[2].FSL-1 activates the MAP kinase NF-κB signaling pathway[2]. Cell Viability Assay[1] Cell Line: V11I, V12I or V19I immortalized human vaginal EC FSL-1 application significantly protectes against genital HSV-2 challenge in mice[1]. Animal Model: Female Swiss-Webster mice (weighing 20-25 g)[1] [1]. William A Rose 2nd, et al.

HDAC3 inhibitor is an allosteric inhibitor of histone deacetylase 3 (HDAC3; Ki = 0.16 nM). It is selective for HDAC3 over HDAC1 and HDAC2 (IC50s = 0.95, 11.81, and 95.45 nM, respectively, using recombinant HDACs). In addition, it is selective for acute myeloid, monocytic, and lymphoblastic leukemia cell lines (EC50s = 36.37, 76.64, and 151.7 nM, respectively) over chronic myeloid, acute promyelocytic, and acute lymphoblastic cells (EC50s = 2,160, >10,000, and >10,000 nM, respectively).

CAY10503 is a proapoptotic, antiproliferative compound that is able to arrest cell cycle progression in the G0-G1 phase. CAY10503 inhibits the growth of HL60, multidrug resistant HL60R, and K562 cells with IC50 values of 7.0, 23, and 20 μM, respectively. Accumulation of HL60 cells in G0-G1 occurred within eight hours following treatment with 50 μM CAY10503, whereas 10 μM CAY10503 required 96 hours for cell cycle arrest to appear. CAY10503 also induces differentiation of HL60 cells into the following positive cells: CD14 (monocytic marker) as well as CD11b and CD11c (granulocytic markers). Approximately 60% of HL60 cells exposed to 10 μM CAY10503 expressed these markers within 72 hours.

The group IVA phospholipase A2 (PLA2), known as calcium-dependent cytosolic PLA2 (cPLA2), selectively releases arachidonic acid (AA) from membrane phospholipids, playing a central role in initiating the synthesis of prostaglandins (PGs) and leukotrienes (LTs). Pyrrophenone inhibits cPLA2α with an IC50 of 4.2 nM in enzyme assays and potently blocks the release of AA and the production of PGE2 and LTC4 in cells (IC50 = 24, 25, and 14 nM, respectively). Its action is reversible and selective, as pyrrophenone inhibits the secretory type IB and IIA PLA2s with more than a hundred-fold less potency. Pyrrophenone has also been shown to inhibit calcium ionophore (A23187)-stimulated AA release from monocytic cells, interleukin-1-induced PGE2 synthesis in mesangial cells, and the production of PGE2, LTs, and platelet-activating factor by human neutrophils, always with maximal inhibition at concentrations below 1 μM.

Aspergillin PZ is a fungal metabolite originally isolated from A. awamori. It induces morphological deformation of P. oryzae conidia when used at a concentration of 89 nM. Aspergillin PZ is active against S. epidermidis (MIC = 20 μM) but not S. aureus, E. coli, or B. cereus (MICs = >20 μM). It is cytotoxic to HL-60 promyelocytic leukemia cells (IC50 = 56.61 μM) but not THP-1 acute monocytic leukemia or PC3 prostate cancer cells (IC50s = >80 μM).

Phytohemagglutinin P（PHA-P，植物血凝素 P）是一种天然的凝集素(lectin)，是PHA的蛋白形式。PHA是选择性T细胞有丝分裂原，可以结合T细胞受体并增强HIV-1的复制。

Prostaglandin E2 Ethanolamide (PGE2-EA) 作为PGE2的类似物，通过COX-2催化内源性大麻素进行氧化而形成，具有可能调控人血以及人单核细胞中促炎细胞因子TNF-α产生的功能。

Lucideric acid A (Lucidenic acid A) 是分离自灵芝的天然产物，可抑制 PMA 诱导的MMP-9活性，具有抵抗肝癌细胞侵袭的作用。

Glycozolidal (Compound 12) 是一种具有抗菌效果的咔唑类生物碱，主要针对牙龈卟啉单胞菌 (P. gingivalis)。它在体外对人牙龈成纤维细胞 (HGFs) 和单核细胞 (U937) 显示出的细胞毒性水平相当，其 IC50 值分别是 120.86 µg mL 和 97.74 µg mL。
