Cycloheximide (Naramycin A) is a natural product . Cycloheximide‘s IC50 values for protein synthesis and RNA synthesis in vivo are 532.5 nM and 2880 nM, respectively. Cycloheximide inhibits ferroptosis and autophagy and is an antifungal antibiotic.

Solasonine exerts leishmanicidal activity against promastigote forms of L. amazonensis.

Halofuginone specifically inhibits collagen type I gene expression and matrix metalloproteinase 2 (MMP-2) gene expression, which may result in the suppression of angiogenesis, tumor stromal cell development, and tumor cell growth. Halofuginone Hydrobromide is the hydrobromide salt of halofuginone, a semisynthetic quinazolinone alkaloid anticoccidial derived from the plant Dichroa febrifuga, with antifibrotic and potential antineoplastic activities. These effects appear to be due to halofuginone-mediated inhibition of the collagen type I and MMP-2 promoters. Collagen type I and MMP-2 play important roles in fibroproliferative diseases.

Halofuginone (RU-19110), the competitive inhibitor of prolyl-tRNA synthetase(Ki=18.3 nM), could also down-regulate Smad3 and blocked TGF-β signaling at 10 ng/ml in the mammal.

1-Deoxynojirimycin (Moranoline) is a potent α-glucosidase inhibitor, suppressing postprandial blood glucose, thereby possibly preventing diabetes mellitus.

Solanidine, a cholestane alkaloid isolated from potato species [Solanum spp.], exhibits antitumor effects by inhibiting cell proliferation.

(-)-Coclaurine hydrochloride is an antagonist of nAChRs isolated from Sarcopetalum harveyanum.

Matrine (Vegard), an alkaloid isolated from the Sophora genus, acts as a kappa opioid receptor agonist.

The biological activity of Jervine (Jerwiny) is mediated via its interaction with the 7 passes transmembrane protein Smoothened. Jervine binds with and inhibits smoothened, which is an integral part of the Hedgehog signaling pathways. With smoothened inhibited, the GLI1 transcription cannot be activated and Hedgehog target genes cannot be transcribed.

Corypalmine is a kind of alkaloid from Coptis chinensis and purple chinensis, which has inhibitory effect on the germination of plant pathogenic spores and saprophytic fungi.

Raloxifene hydrochloride (LY156758 hydrochloride) is a second generation selective estrogen receptor modulator (SERM) used to prevent osteoporosis in postmenopausal women. It has estrogen agonist effects on bone and cholesterol metabolism but behaves as a complete estrogen antagonist on mammary gland and uterine tissue.

Anabasine ((S)-Anabasine) is an alkaloid extracted from tobacco, acting as a full agonist of nicotinic acetylcholine receptors (nAChRs) with insecticidal activity. It depolarizes TE671 cells that endogenously express human myotypic nAChRs.

Minoxidil (U10858) is an orally administered vasodilator with hair growth stimulatory and antihypertensive effects.

Quinine dihydrochloride (Quinine bimuriate) is a primary alkaloid of various species of Cinchona (Rubiaceae). It is also an antimalarial and muscle relaxant (skeletal).

Sinomenine (Kukoline) is a pure alkaloid isolated from the Sinomenium acutum, is utilized in the treatment of rheumatism and arthritis.

Arecoline is a natural alkaloid derived from areca nut in the palm family and is a potent nicotine and partial agonist of muscarinic acetylcholine receptors. Arecoline has anti-anxiety and anti-parasitic activity, can induce oxidative stress and can be used to study Alzheimer's disease and Alzheimer's disease.

Oxymatrine (Oxysophoridine) is an alkaloid isolated from Sophora flavescens, used as the antibiotic. It is a traditional Chinese medicine used in the treatment against hepatitis B virus.It can also inhibit iNOS expression and TGF - β / Smad pathway.

N-Formylcytisine ((-)-N-Formylcytisine) is a natural product isolated from the stem bark of Maackia amurensis.

Veratramine (NSC-23880)(NSC-17821; NSC-23880) is a potent signal transduction inhibitor for treating tumors.

Neoline is an active ingredient of A. venetum root (PA) that ameliorates oxaliplatin-induced peripheral neuropathy in mice.Neoline inhibits Nav1.7 voltage-gated sodium channel currents (VGSC). It can be used as a labeling compound to determine the quality of PA products used in the study of neuropathic pain.

1. Peiminine (Raddeanine) is an effective inhibitor for lung inflammation and pulmonary fibrosis in a rat model of bleomycin-induced lung injury.

1. Sipeimine (Kashmirine) has antiasthmatic effect, on tracheal M receptor antagonist. 2. Sipeimine can make Kaba cholinergic induced contraction of tracheal strips of the dose-response curve to the right.

Pseudojervine (O-beta-D-Glucopyranosyljervine) is derived from Veratrum nigrum L. Pseudojervine exhibits feeble inhibition activity against platelet aggregation.
