4-Hydroxyisoleucine is an isoleucine derivative. 4-Hydroxyisoleucine has antidepressant-like, antidyslipidemic, and antihyperglycemic effects. It acts to improve insulin resistance by promoting mitochondrial biogenesis in high fructose diet fed STZ induced diabetic rats, it also has beneficial effects on low-grade inflammation. 4-Hydroxyisoleucineis an orally active amino acid that can be isolated from fenugreek seeds. 4-Hydroxyisoleucine has insulin promoting and anti diabetes properties.

L-threonine is an optically active form of threonine having L-configuration. It has a role as a micronutrient, a nutraceutical, a mouse metabolite, a Saccharomyces cerevisiae metabolite, a plant metabolite, an Escherichia coli metabolite, a human metabolite and an algal metabolite. It is a L-alpha-amino acid, an aspartate family amino acid, a threonine and a proteinogenic amino acid. It is a conjugate base of a L-threoninium. It is a conjugate acid of a L-threoninate. L-Threonine is a natural amino acid, can be produced by microbial fermentation, and is used in food, medicine, or feed.

Bilobalide possesses anticonvulsant, insecticidal, and cardioprotective effects. Bilobalide exerts protective and trophic effects on neurons, the PI3K/Akt pathway may be involved in the protective effects of bilobalide; it also can protect PC12 cells from A beta 25-35-induced cytotoxicity, it dose-dependently attenuates the cytotoxic effect of A beta 25-35. Bilobalide is a terpenoid trilactone found in extracts of Ginkgo biloba.

Marinobufagenin is a cardiotonic steroid secreted by the toad Bufo rubescens and other related species such as Bufo marinus. An endogenous Na/K-ATPase inhibitor, it is a vasoconstrictor with effects similar to digitalis. It has a role as an epitope and an EC 3.6.3.9 (Na(+)/K(+)-transporting ATPase) inhibitor. It is an epoxy steroid and a steroid hormone. It is functionally related to a (5beta)-bufadienolide.
