S5148 2-Methylenebutyrolactone 2-Methylenebutyrolactone (Tulipalin A, MBL, α-methylene-γ-butyrolactone), also known as α-methylene-γ-butyrolactone (MBL) (Tulipalin A), belongs to the class of sesquiterpene lactone family and is considered as cyclic analog of most common vinyl monomer methyl methacrylate (MMA).
S5681 Vinburnine Vinburnine ((-)-Eburnamonine, Vincamone, L-Eburnamonine) is a vasodilator. It is a vinca alkaloid and a metabolite of vincamine.
E7243 N-Desethyl Sunitinib N-Desethyl Sunitinib (SU-12662) is a metabolite of sunitinib. Sunitinib is a potent, ATP-competitive VEGFR, PDGFRβ and KIT inhibitor with Ki values of 2, 9, 17, 8 and 4 nM for VEGFR -1, -2, -3, PDGFRβ and KIT, respectively.
E4608 4-Hydroperoxy cyclophosphamide 4-Hydroperoxy cyclophosphamide is the active metabolite form of the precursor Cyclophosphamide. 4-Hydroperoxy cyclophosphamide cross-links DNA to induce T cell apoptosis independent of caspase receptor activation, and can activate the mitochondrial death pathway by producing reactive oxygen species (ROS). 4-Hydroperoxy cyclophosphamide can be used in the study of rheumatoid arthritis and autoimmune diseases.
S5672 Hydroxyhexamide Hydroxyhexamide is a pharmacologically active metabolite of acetohexamide, which is a sulfonylurea hypoglycemic agent.
E4922 Allopurinol riboside Allopurinol riboside, a metabolite of allopurinol, competitively inhibits the action of purine nucleoside phosphorylase on inosine in vitro with a Ki value of 277 μM. It displays potent activities against parasites.
E7914 Desisobutyryl-ciclesonide Desisobutyryl-ciclesonide is the active metabolite of ciclesonide. It exhibits potent anti-inflammatory activity by effectively inhibiting allergen-induced T-cell proliferation and interleukin-4 expression in vitro and that may have clinical relevance.
S6014 Isonicotinic acid Isonicotinic acid (Isoniazid, 4-pyridinecarboxylic acid, p-pyridinecarboxylic acid, 4-Picolinic acid) is a metabolite of isoniazid. It is an isomer of nicotinic acid.
S5826 Monobutyl phthalate Monobutyl phtalate is a metabolite of di(n-butyl)phthalate. It affects the expressions of EMT-related proteins and enhances the migration and invasion of MLTC-1 cells.
