Lipid Classification

?8,9-Dehydro Estrone-d₂ is the deuterium labeled ?8,9-Dehydro Estrone.

Lithocholic acid 3-sulfate-d₄（sodium salt） is the deuterium labeled Lithocholic acid 3-sulfate.

Calcitriol-¹³C₃ is the ¹³C-labeled Calcitriol. Calcitriol is the most active metabolite of vitamin D and also a vitamin D receptor (VDR) agonist.

7-Keto Cholesterol-d₇ is the deuterium labeled 7-Keto Cholesterol.

Menaquinone-7-d₇ is the deuterium labeled Menaquinone-7. Menaquinone-7 (Vitamin K2-7), belongs to a class of K2-vitamin homologs, is originally discovered as the anti-hemorrhagic factors. Menaquinone-7 (Vitamin K2-7) is identified as the most bioactive cofactor for the carboxylation reaction of Gla-proteins . Supplementation with Menaquinone-7 (Vitamin K2-7) is a pharmacological option for activating matrix Gla protein and intervening in the progression of calcific aortic valve stenosis (CAVS).

β-Tocopherol-d₃ is the deuterium labeled β-Tocopherol. β-Tocopherol is an analogue of vitamin E, exhibits antioxidant properties. β-Tocopherol can inhibit tyrosinase activity and melanin synthesis. β-Tocopherol can also prevent the inhibition of cell growth and of PKC activity caused by d-alpha-tocopherol.

Taurocholic acid 3-sulfate-d₄ (disodium) is the deuterium labeled Taurocholic acid 3-sulfate disodium.

Adapalene (CD271) sodium salt, a third-generation synthetic retinoid, is widely used for the research of acne. Adapalene sodium salt is a potent RAR agonist, with AC₅₀s of 2.3 nM, 9.3 nM, and 22 nM for RARβ, RARγ, RARα, respectively. Adapalene sodium salt also inhibits the enzymatic activity of GOT1 in a non-competitive manner. Adapalene sodium salt exhibits anti-tumor activity.

Leucic acid-¹³C (α-Hydroxyisocaproic acid-¹³C) is the ¹³C-labeled Leucic acid (HY-30216A). Leucic acid is an amino acid metabolite.

DPPC-¹³C₃ (129Y83-¹³C) is the ¹³C-labeled DPPC (HY-109506). DPPC (129Y83) is a phosphoglyceride that can be used to prepare lipid monolayers, bilayers, and liposomes. DPPC is the main lipid component of pulmonary surfactant. Dppc-liposome can be effectively used as a delivery vector to induce an immune response against GSL antigen in mice.

Limocitrin 3-β-D-glucose is a flavonoid glycoside.

DL-threo-2-methylisocitrate is a substrate of isocitrate lyase 1(ICL1).

Complanatoside A is a flavonol glycoside isolated from Astragalus complanatus, and currently it is used as a quality control index for A. complanatus in the 2010 edition of the Chinese Pharmacopoeia.
