Stephania japonica (Thunb.) Miers

Cepharanthine is a natural product that can be isolated from the plant Stephania cephalantha Hayata. Cepharanthine has anti-severe acute respiratory syndrome coronavirus 2 (anti-SARS-CoV-2) activities. Cepharanthine has good effective in suppressing viral proliferation (half maximal (50%) inhibitory concentration (IC₅₀) and 90% inhibitory concentration (IC₉₀) values of 1.90 and 4.46 μM. Cepharanthine can also effectively reverses P-gp-mediated multidrug resistance in K562 cells and increase enhances the sensitivity of anticancer agents in xenograft mice model. Cepharanthine shows inhibitory effects of human liver cytochrome P450 enzymes CYP3A4, CYP2E1 and CYP2C9. Cepharanthine has antitumor, anti-inflammatory and antinociceptive effects.

Cyclen is a macrocyclic tetraamine chelating agent. Cyclen is the aza analogue of crown ether, used as a precursor for MRI contrast agents, and is an intermediate for the preparation of effective macrocyclic chelates. Cyclen is employed as a structural regulator through interfacial polymerization of polyethleneimine (PEI) and trimesoyl chloride (TMC) to develop polyamide NF membrane with efficient Li⁺/Mg²⁺ separation performance. Cyclen has specific cavity structure and exhibits selective coordination properties for Li⁺ ions^[1][2].

Cepharanthine (Standard) is the analytical standard of Cepharanthine. This product is intended for research and analytical applications. Cepharanthine is a natural product that can be isolated from the plant Stephania?cephalantha?Hayata. Cepharanthine has anti-severe acute respiratory syndrome coronavirus 2 (anti-SARS-CoV-2) activities. Cepharanthine has good effective in suppressing viral proliferation (half maximal (50%) inhibitory concentration (IC₅₀) and 90% inhibitory concentration (IC90) values of 1.90 and 4.46?μM. Cepharanthine can also effectively reverses P-gp-mediated multidrug resistance in K562 cells and increase enhances the sensitivity of anticancer agents in xenograft mice model. Cepharanthine shows inhibitory effects of human liver cytochrome P450 enzymes CYP3A4, CYP2E1 and CYP2C9. Cepharanthine has antitumor, anti-inflammatory and antinociceptive effects.

Stephalonine P is a hasubanan-type alkaloid anti-inflammatory agent with neuroprotective effects against neuroinflammation. Stephalonine P regulates post-ischemic inflammatory responses by inhibiting NO production in LPS-activated BV2 microglia (IC₅₀=34.01 μM), thereby reducing microglial activation and neuronal damage. Stephalonine P can be isolated from the whole plant of Stephania japonica. Stephalonine P can be used in research on stroke and other neuroinflammation-related diseases.

Stephalonine M is a natural alkaloid.

Oxoepistephamiersine is a natural alkaloid.

Stephalonine L is a natural alkaloid.

Stephanine ((-)-Stephanine) is an isoquinoline aporphine-type alkaloid. Stephanine induce apoptosis through the reverse of mitotic exit. Stephanine exhibits Antiplasmodial activity. Stephanine can be used for the research of stomach pain, abdominal pain, arthritis and cancer.

Sinococuline is a potent anti-dengue agent that is effective against all four serotypes of dengue virus (DENV). Sinococuline is also an effective tumor cell growth inhibitor.

Homostephanoline is a corydane-type alkaloid that can be isolated from species of the Stephania subgenus.

Cyclen (Standard) is the analytical standard substance of Cyclen. This product is used for research and analytical applications. Cyclen is a macrocyclic tetrathiolate chelating agent. Cyclen is a nitrogen-containing analogue of crown ethers and can be used as a precursor for MRI contrast agents, as well as an intermediate for preparing highly efficient macrocyclic chelates. As a structural regulator, Cyclen can be prepared into polyamide nanofiltration membranes with efficient Li⁺/Mg²⁺ separation performance through the interfacial polymerization of polyethyleneimine (PEI) and meta-benzotriazole chloride (TMC). Cyclen has a unique cavity structure and exhibits selective coordination properties for Li⁺ ions.
