Wnt-C59 (C59) is a highly potent and oral porcupine (PORCN) inhibitor with an IC₅₀ of 74 pM.

Dihydroartemisinin is an orally active metabolite of rtemisinin (HY-B0094) and antimalarial agent. Dihydroartemisinin induces Autophagy by inhibiting NF-κB activation. Dihydroartemisinin promotes ROS accumulation. Dihydroartemisinin exhibits anticancer activity in esophageal cancer cells. Dihydroartemisinin shows schistosomicidal activity against juvenile and adult worms of Schistosoma japonicum, reduces worm burden, and displays antiparasitic activity. Dihydroartemisinin can be used in research related to multiple myeloma, promyelocytic leukemia, esophageal cancer, and Schistosoma japonicum infection.

Ponatinib (AP24534) is an orally active multi-targeted kinase inhibitor with IC₅₀s of 0.37 nM, 1.1 nM, 1.5 nM, 2.2 nM, and 5.4 nM for Abl, PDGFRα, VEGFR2, FGFR1, and Src, respectively.

Dexamethasone phosphate (Dexamethasone 21-phosphate) disodium is a prodrug form of the glucocorticoid Dexamethasone (HY-14648). Dexamethasone phosphate disodium is produced by introducing a phosphate ester group at the 21-position of the Dexamethasone molecule, forming a salt with sodium ions, thereby significantly improving water solubility. Dexamethasone phosphate disodium inhibits LPS (HY-D1056)-induced degradation of IRAK-1 and IRAK-4, and blocks LPS-induced activation of TRAF6, p-TAK1 and p-JNK. Dexamethasone phosphate disodium inhibits the secretion of RANTES, TGF-β1 and NO, promotes the production of MIP-1α and IL-10, and blocks microglial migration. Dexamethasone phosphate disodium is almost completely converted to Dexamethasone in rat blood, and supports transdermal delivery via iontophoresis. Dexamethasone phosphate disodium can be used in research related to steroid-dependent ulcerative colitis, chemotherapy-induced vomiting, allergic asthma and acute colitis (inflammatory bowel disease).

GY4137 is a sustained-release H2S donor possessing vasodilatory, antihypertensive, and anti-inflammatory activities. GY4137 can inhibit cell growth, induce apoptosis, and cause cell cycle arrest by blocking the STAT3 pathway, demonstrating potent anticancer activity.

Taurocholic acid (N-Choloyltaurine) has marked bioactive effects such as an inhibitory potential against hepatic artery ligation induced biliary damage by upregulation of VEGF-A expression. Taurocholic acid has immunoregulation effect.

Cyclic AMP (Cyclic adenosine monophosphate), adenosine triphosphate derivative, is an intracellular signaling molecule responsible for directing cellular responses to extracellular signals. Cyclic AMP is an important second messenger in many biological processes.

L-Cysteine (Cysteine) is an orally active conditionally essential amino acid with hypoglycemic effects, which acts as a precursor for biologically active molecules such as hydrogen sulphide (H2S), glutathione and taurine. L-Cysteine promotes the proliferation and differentiation of neural stem cells via the CBS/H2S pathway. L-Cysteine suppresses ghrelin and reduces appetite in rodents and humans. L-Cysteine can be used as an anorectic agent.

Busulfan is a potent alkylating antineoplastic agent. Busulfan causes DNA damage by cross-linking DNAs and DNA and proteins. Busulfan inhibits thioredoxin reductase. Busulfan induces apoptosis. Busulfan is an immunosuppressive and myeloablative chemotherapeutic agent.

Rolipram is a PDE4 inhibitor, with blood-brain barrier permeability, that reverses β-amyloid-induced learning and memory impairment in rats. Rolipram elevates intracellular cAMP and clevels and regulates the cAMP/CREB signaling pathway, thereby alleviating neuroinflammation and apoptotic responses. Rolipram promotes neuronal differentiation of human bone marrow mesenchymal stem cells and inhibits Methamphetamine- and morphine-induced hyperlocomotion in mice. Rolipram also reduces the viability of glioblastoma stem-like cells and enhances Bevacizumab (HY-P9906)-induced cell death. Rolipram inhibits the expression of proinflammatory cytokines and enhances central noradrenergic transmission. Rolipram is mainly used in studies related to various central nervous system diseases including Alzheimer's disease, major depressive disorder, glioblastoma multiforme, and multiple sclerosis.
