Chlorphenoxamine (Contristamine) is an antihistamine and anticholinergic utilized as an antipruritic and antiparkinsonian agent.

Thalifendine chloride is a metabolite of berberine, wherein the methoxy group at the C-10 position undergoes demethylation by CYP51. It exhibits cytotoxicity against P-388 mouse leukaemia cells (ED₅₀ = 0.84 μM) and demonstrates weak inhibitory activity against Plasmodium falciparum.

(S)-Higenamine ((S)-Norcoclaurine), the S-enantiomer vital for benzylisoquinoline alkaloid biosynthesis, is synthesized from dopamine and 4-hydroxyphenylacetaldehyde (4-HPAA) through norcoclaurine synthase (NCS) catalysis [1].

Corydalmine hydrochloride is a chemical compound that suppresses spore germination in certain plant pathogenic and saprophytic fungi [1], serves as an effective oral analgesic agent with potent activity [2], and mitigates Vincristine-induced neuropathic pain in mice through the inhibition of an NF-κB-dependent CXCL1/CXCR2 signaling pathway [3].

Isoxanthohumol is a prenylated flavonoid derived from hops and beer with antiproliferative activity against several human cancer cell lines.Isoxanthohumol inhibits the metastasis or invasion of lung metastases of tumor cells.Isoxanthohumol has antiviral activity against herpesviruses (HSV1 and HSV2) and bovine viral diarrhea virus (BVDV).

Lupanine hydrochloride, a natural ketonic derivative of Sparteine ((+)-Sparteine), exhibits ganglioplegic activity and binds to the nicotinic receptor (nAChR) with a K i value of 500 nM [1].

Echitamine chloride, the predominant monoterpene indole alkaloid found in Alstonia scholaris, exhibits significant anti-tumor activity by inducing DNA fragmentation and apoptosis. Furthermore, it effectively inhibits pancreatic lipase, with an inhibition concentration (IC 50) of 10.92 µM [1] [2].

Nostosin G, a linear peptide, comprises three subunits: 4-hydroxyphenyllactic acid (Hpla), homotyrosine (Hty), and argininal. It exhibits a potent trypsin inhibitory effect, demonstrated by an IC 50 value of 0.1 μM [1].

Rivulariapeptolides 1155 is a potent serine protease inhibitor with inhibitory concentrations (IC50s) of 41.84 nM, 4.94 nM, and 56.54 nM against chymotrypsin, elastase, and proteinase K, respectively [1].

Rivulariapeptolides 1185, a highly potent and selective serine protease inhibitor, exhibits IC50 values of 13.17 nM for chymotrypsin, 23.59 nM for elastase, and 55.26 nM for proteinase K [1].
