S9374	2',5'-Dihydroxyacetophenone	2',5'-Dihydroxyacetophenone (DHAP, 2-Acetylhydroquinone, Quinacetophenone) is a mixture of dihydroxyacetophenone isomers is used in food flavouring. 2',5'-Dihydroxyacetophenone significantly inhibits NO production via the suppression of iNOS expression. 2',5'-Dihydroxyacetophenone significantly decreases levels of the pro-inflammatory cytokines TNF-α and IL-6 by blocking the ERK1/2 and NF-κB signaling pathways.	Selective
S3292	Falcarindiol	Falcarindiol (FAD, (3R,8S)-Falcarindiol, FaDOH) is a natural polyacetylene compound found rich in many plants of the Umbelliferae family. Falcarindiol suppresses LPS-stimulated expression of inducible nitric oxide synthase (iNOS), tumor necrosis factor alpha (TNFα), interleukin-6 (IL-6), and interleukin-1 beta (IL-1β). Falcarindiol attenuates the LPS-induced activation of JNK, ERK, STAT1, and STAT3 signaling molecules.	Selective
S3304	Stylopine	Stylopine ((R,S)-Stylopine, Tetrahydrocoptisine) reduces nitric oxide (NO), prostaglandin E2 (PGE2), tumor necrosis factor-alpha (TNF-alpha) and interleukin-1beta (IL-1beta), and the IL-6 production and cyclooxygenase-2 (COX-2) activity caused by the LPS stimulation. Stylopine is a major component of the leaf of Chelidonium majus L.	Selective
S6962	TPEN	TPEN (TPEDA) is a specific cell-permeable heavy metal chelator that induces apoptosis in NB4 cells via negatively regulating intracellular NO and Zn²⁺ signaling. TPEN (TPEDA) may be a potential therapeutic strategy for APL (acute promyelocytic leukemia).TPEN induces DNA damage and increases intracellular ROS production and also inhibits cell proliferation.	Selective
S3899	Hederagenin	Hederagenin (Caulosapogenin, Hederagenol, Hederagenic acid, Astrantiagenin E) is a highly water insoluble triterpenoid compound that can be found in various plants including Hedera helix and Chenopodium quinoa. It exhibits a variety of biological activities, including potent antitumor properties both in vitro and in vivo. Hederagenin inhibits LPS-stimulated expression of iNOS, COX-2, and NF-κB.	Selective
S5671	Amcinonide	Amcinonide (Cyclocort, CL-34699) is an inhibitor of nitric oxide (NO) release from activated microglia with IC50 of 3.38 nM.	Selective	NO, IC50: 3.38 nM
S8337	1400W 2HCl	1400W (N-(3-(Aminomethyl)benzyl)acetamidine) is a slow, tight binding, and highly selective inhibitor of inducible nitric-oxide synthase(iNOS).	Selective	iNOS, Kd: <7 nM
S0924	Pteryxin	Pteryxin ((+)-Pteryxin), a dihydropyranocoumarin derivative found in Apiaceae family, is a potent inhibitor of butyrylcholinesterase (BChE) with IC50 of 12.96 μg/ml. Pteryxin inhibits LPS-induced nitric oxide production in mouse peritoneal macrophages with IC50 of 20 µM. Pteryxin is potential for Alzheimer's disease (AD) treatment.	Selective	nitric oxide, IC50: 20 μM
S3261	Myrislignan	Myrislignan, a lignan isolated from Myristica fragrans Houtt, possesses anti-inflammatory activities. Myrislignan inhibits interleukin-6 (IL-6) and tumour necrosis factor-α (TNF-α). Myrislignan significantly inhibits the expressions of inducible NO synthase (iNOS) and cyclooxygenase-2 (COX-2) dose-dependently in LPS-stimulated macrophage cells. Myrislignan inhibits the NF-κB signalling pathway activation.	Selective
S9502	Madecassic acid	Madecassic acid (Brahmic acid), a natural triterpene first isolated from C. asiatica, has diverse anti-inflammatory and anti-diabetic effects, blocking NF-κB activation in macrophages and causing by iNOS, COX-2, TNF-alpha, IL-1beta and IL-6 inhibition.	Selective
S3924	Ginsenoside Rb1	Ginsenoside Rb1 (Gypenoside Ⅲ) is a protopanaxadiol that has diverse in vitro and in vivo effects, including neuroprotective, anti-inflammatory, and anti-obesity actions. Ginsenoside Rb1, a main constituent of the root of Panax ginseng, inhibits Na+, K+-ATPase activity with IC50 of 6.3±1.0 μM. Ginsenoside also inhibits IRAK-1 activation and phosphorylation of NF-κB p65. Ginsenoside Rb1 reduces the expressions of TLR3, TLR4 and TRAF-6, and down-regulates	Selective
