Hypocrellin A, an a natural perylene quinine photosensitizers (PSs), can chelate with heavy metal ions, including Au(III) and Pt(IV), to form a 1:2 complex. Hypocrellin A has light-induced antitumor,antifungal and antiviral activities, it also exerts immunomodulatory effects on MHC-restricted presentation of antigen.

Hellebrigenin is a steroid aldehyde, a steroid lactone, a 3beta-hydroxy steroid, a 14beta-hydroxy steroid, a 19-oxo steroid and a 5beta-hydroxy steroid. It has a role as an autophagy inducer, an antineoplastic agent, an apoptosis inducer, an antileishmanial agent, an animal metabolite and a plant metabolite. It is functionally related to a 5beta-bufanolide.

Gymnestrogenin has a dual LXRα/β antagonistic profile.

Ganoderol A has significant anti-inflammatory activity and protection against UVA damage. it has an inhibitory effect on angiotensin converting enzyme activity and cholesterol biosynthesis.

Isovalerylshikonin, a new resistance-modifying agent from Arnebia euchroma, supresses antimicrobial resistance of drug-resistant Staphylococcus aureus; it also has anti-mite activity. Isovalerylshikonin as a candidate of AChE inhibitor, it may prevent apoptotic cell death induced by hydrogen peroxide in human and rat neuronal SH-SY5Y and PC12 cells.

Rebaudioside B is a rebaudioside that is steviol in which the hydroxy group is replaced by a beta-D-glucopyranosyl-(12)-[beta-D-glucopyranosyl-(13)]-beta-D-glucopyranosyl group. It has a role as a sweetening agent. It is a rebaudioside, a beta-D-glucoside and a trisaccharide derivative. It is functionally related to a beta-D-Glcp-(1->2)-[beta-D-Glcp-(1->3)]-beta-D-Glcp. It is a conjugate acid of a rebaudioside B(1-). Rebaudioside B tastes about 150 times sweeter than sucrose and it is non-caloric.

L-methionine is the L-enantiomer of methionine. It has a role as a micronutrient, a nutraceutical, an antidote to paracetamol poisoning, a mouse metabolite and a human metabolite. It is a L-alpha-amino acid, a methionine, an aspartate family amino acid and a proteinogenic amino acid. It is a conjugate base of a L-methioninium. It is a conjugate acid of a L-methioninate. It is an enantiomer of a D-methionine. It is a tautomer of a L-methionine zwitterion. L-Methionine is marker of cell viability and estimating proliferative activity. L-Methionine and L-cystine can improve hyperlipidemia by restoring LPL and HSL activities, it also might be a new potential drug for Parkinson's disease treatment.
