Pellitorine (Pellitorin) is an extract of Tetradium daniellii, and acts as a TRPV1 antagonist.

MYCMI-6 (NSC-354961) is a potent and selective inhibitor of endogenous MYC:MAX protein interactions,reduces proliferation and induces massive apoptosis in tumor tissue from a MYC-driven xenograft tumor model without severe side effects.

NBDHEX is a potent inhibitor of glutathione S-transferase P1-1 (GSTP1-1) .

MS1943 is a orally bioavailable EZH2 selective degrader(IC50 of 120 nM).

ARM1 is a potent inhibitor of aminopeptidase and epoxide hydrolase. The IC50 values are 7.61 µM for aminopeptidase and 12.4 µM for epoxide hydrolase.

Jatrorrhizine (neprotin) is a protoberberine alkaloid isolated from Enantia chlorantha (Annonaceae) and other species. It was found to have antimicrobial and antifungal activity. It binds and noncompetitively inhibits monoamine oxidase (IC50 4 micromolar for MAO-A and 62 for MAO-B).

Jatrorrhizine chloride (Neprotine chloride) is a potent and orally active uptake-2 transporter inhibitor. It exhibits a critical neuroprotective role in H2O2-induced apoptosis via inhibition of the MAPK pathway in HT22 hippocampal neurons.

STF-62247 is TGN inhibitor with IC50 of 0.625 μM and 16 μM in RCC4 and RCC4/VHL cells, respectively.

SKI-178 is a sphingosine kinase 1 (SphK1) inhibitor with IC50 of 0.1-1.8 μM. It induces prolonged mitosis followed by apoptotic cell death through the intrinsic apoptotic cascade. The sustained activation of CDK1 during prolonged mitosis, mediated by SKI-178 leads to the simultaneous phosphorylation of the prosurvival Bcl-2 family members, Bcl-2 and Bcl-xl, as well as the phosphorylation and subsequent degradation of Mcl-1.

Hamamelitannin has cytotoxic, and antibiofilm activities. It increases the susceptibility of S. aureus to antibiotic treatment in in vivo Caenorhabditis elegans and mouse mammary gland infection models. It also has a high protective activity on cell damag

Matairesinol 4′-O-β-D-glucopyranoside is a natural product isolated from *Trachelospermum jasminoides*.

Sarracenin is a natural product. Sarracenin shows cytotoxic activities against tumor cells.

Tectol has anti-plasmodial activity, it as a moderately active growth inhibitor with an IC50 3.44±0.20μM. It exhibited significant activity against human leukemia cell lines HL60 and CEM. Tectol may cause itchy dermatitis, the dermatitis appeared on the n

Neolancerin is a natural product isolated from adventitious roots of St. John's wort (Hypericum perforatum L.).

Acifluorfen is a protoporphyrinogen oxidase (PPO) inhibitor herbicide that promotes the accumulation of protoporphyrin IX. It induces liver tumors, liver injury, and cardiac dysfunction in rodents, and causes severe photooxidative damage to pigments and lipids in susceptible plants. It can be used to induce hepatitis and pancreatitis.

Doxorubicin hydrochloride is an anthracycline antibiotic with cytotoxic and antitumor activity. It is an effective inhibitor of human DNA topoisomerase I and II, with IC50 values of 0.8 μM and 2.67 μM, respectively. In addition to inhibiting DNA topoisomerases, it can reduce the phosphorylation of AMPK and its downstream target, acetyl-CoA carboxylase. Doxorubicin hydrochloride also induces apoptosis and autophagy. In animal studies, it is commonly used to induce models of acute renal failure, chronic kidney injury, and heart failure.

DZ2002, an orally active, reversible, and low-cytotoxic type III SAHH inhibitor (Ki=17.9 nM), exhibits significant immunosuppressive activity. It effectively prevents experimental dermal fibrosis by reversing the profibrotic phenotype in multiple cell types, making it useful for studying autoimmune diseases like lupus syndrome and systemic sclerosis.
