Activators & Inhibitors

9(S)-HpOTrE (Legacy Tebubio ref. 282T37867). 9(S)-HpOTrE, a monohydroperoxy polyunsaturated fatty acid, is produced by the action of 5-lipoxygenase (5-LO) on α-linolenic acid. It can be metabolized to colnelenic acid by a divinyl ether synthase activity found in garlic and potato microsomal fractions. 9(S)-HpOTrE also serves as a substrate for further oxidation by both soybean and potato LOs, resulting in 9,16-dihydroperoxy acid formation. The suicide inactivation of LOs when 9(S)-HpOTrE is used as a substrate is thought to occur via the formation of an unstable epoxide.

9-OxoOTrE (Legacy Tebubio ref. 282T37868). 9-OxoOTrE is produced by the oxidation of 9-HpOTrE. 9-OxoOTrE exhibits antimicrobial activity against plant pathogenic microorganisms including bacteria and fungi.

BODIPY aminoacetaldehyde (Legacy Tebubio ref. 282T37869). BODIPY aminoacetaldehyde (BAAA) is a fluorescent substrate for aldehyde dehydrogenase (ALDH) and can be used to isolate human hematopoietic stem cells based on ALDH activity.

Tomatine hydrochloride (Legacy Tebubio ref. 282T3786L). Tomatine hydrochloride is an alkaloid that occurs in the extract of leaves of wild tomato plants. It inhibits the growth of many fungi and bacteria. It is used as a precipitating agent for steroids.

Didymin (Legacy Tebubio ref. 282T3787). Didymin (Neoponcirin) has antioxidant property. Didymin induces apoptosis by inhibiting N-Myc and upregulating RKIP in neuroblastoma, may used for neuroblastoma therapy. Didymin may be a potential therapeutic molecule for the treatment of neurodegenerative disorders associated with oxidative stress.

Bz-Nle-Lys-Arg-Arg-AMC (Legacy Tebubio ref. 282T37870). Substrate for dengue virus NS2B-NS3 and yellow fever virus NS3 protease. The kcat/Km value of Bz-NleKRR-AMC for the dengue virus type 4 (DEN4) enzyme is > 800 fold higher than that of Boc-Gly-Arg-Arg-AMC, a widely used NS3 substrate (kcat = 2.9 s 1, Km = 8.6 μM for DEN4). For yellow fever virus NS3 protease the kcat value was 0.111 s 1, the Km value 14.6 μM.

Octaethylene glycol monododecyl ether (Legacy Tebubio ref. 282T37871). C12E8 is a nonionic surfactant formed by the ethoxylation of dodecanol, yielding a compound with eight repeated units of ethylene glycol. It can be used for solubilization of membrane-bound proteins.

C16 Galactosylceramide (d18:1/16:0) (Legacy Tebubio ref. 282T37872). C16 Galactosylceramide is a glycosphingolipid that contains a galactose moiety attached to a ceramide acylated with palmitic acid .

CAP 3 (Legacy Tebubio ref. 282T37873). CAP 3 is a cholic acid-peptide conjugate (CAP) with antibacterial activity. It is active against the Gram-negative bacteria E. coli, K. pneumoniae, and A. baumanii (MIC99s = 8, 16, and 16 μM, respectively). CAP 3 increases the fluidity of model Gram-negative bacterial membranes and binds to LPS in vitro. It reduces the biomass and number of colony-forming units in E. coli biofilms in a concentration-dependent manner. CAP 3 inhibits E. coli biofilm formation on catheters implanted in mice infected with E. coli at the incision site when applied as a coating on the catheters. CAP 3 (40 mg/kg) also reduces bacterial load in E. coli-infected wounds in mice. It is cytotoxic to A459 cells (IC50 = 56.4 μM) and has hemolytic activity against human red blood cells with a 50% lysis (HC50) value of 48 μM.
