noncompetitive

D-Menthol ((+)-MENTHOL) is a common compound in pharmaceutical and commercial products and a popular additive to cigarettes, it attenuates α±7 mediated Ca 2+ transients in the cell body and neurite, suggests that menthol inhibits α±7-nACh receptors in a noncompetitive manner.

6-Hydroxyflavone (6-HF) is a noncompetitive inhibitors of cytochrome P450 2C9. It is a flavone, a type of chemical compound. It is reported in leaves of Barleria prionitis Linn. (a common Acanthaceae from India). 6-Hydroxyflavone may have a potential as a therapeutic drug capable for the treatment of anxiety-like disorders.

1. 3-Butylidenephthalide (Butylidene phthalide) has antihyperglycemic effect is due to inhibition of α-glucosidase at the intestinal level, inhibited the activity of yeast-α-glucosidase (IC(5) 2.35 mM) in a noncompetitive fashion with a K(i) of 4.86 mM.

L-Chicoric Acid (trans-Caffeoyltartaric acid) has been shown to inhibit hyaluronidase and HIV-1 integrase, and to possess phagoeytosis stimulatory activity in vitro and in vivo and antiviral acitivy. L-Chicoric acid may reduce acute alcohol-induced steatosis in mice through interfering with the induction of iNOS and iNOS-dependent signaling cascades in the liver. 3. L-Chicoric acid inhibited cell viability and induced apoptosis in 3T3-L1 preadipocytes which was characterized by chromatin condensation and poly ADP-ribose-polymerase (PARP) cleavage.

Guanfu base A is a potent noncompetitive CYP2D6 inhibitor (Ki: 1.20 μM in HLMs; Ki: 0.37 μM for rCYP2D6). It also inhibits HERG channel current.

beta-Eudesmol (Beta-Selinenol) is a noncompetitive antagonist of nicotinic acetylcholine receptors (nAChRs). It is a sesquiterpene that has been found in a variety of plants, including Cannabis, and has diverse biological activities.

Methyl rosmarinate is a noncompetitive tyrosinase inhibitor isolated from Rabdosia serra, with an IC50 of 0.28 mM for mushroom tyrosinase. It exhibits antioxidative and antifungal activities, and also inhibits tyrosinase, α±-glucosidase, and matrix metalloproteinase-1 (MMP-1).

2'-Deoxyadenosine-5'-triphosphate (dATP) is a purine nucleotide and derivative of the nucleic acid adenosine 5'-triphosphate .1dATP is a substrate for DNA polymerase in the synthesis of DNA.2It is a noncompetitive inhibitor of ribonucleotide reductases, which provides feedback inhibition during DNA synthesis.1dATP has commonly been used in DNA synthesis, sequencing, and labeling in research applications.3,4dATP accumulates in adenosine deaminase deficiency, a disorder characterized by mutations in the gene for adenosine deaminase, the enzyme that catalyzes the deamination of adenosine and deoxyadenosine.5 1.Berg, J.M., Tymoczko, J.L., and Stryer, L.Key steps in nucleotide biosynthesis are regulated by feedback inhibitionBiochemistry(2002) 2.Berg, J.M., Tymoczko, J.L., and Stryer, L.DNA is replicated by polymerases that take instructions from templatesBiochemistry(2002) 3.Cadwell, R.C., and Joyce, G.F.Randomization of genes by PCR mutagenesisPCR Methods Appl.2(1)28-33(1992) 4.Steffens, D.L., Jang, G.Y., Sutter, S.L., et al.An infrared fluorescent dATP for labeling DNAGenome Res.5(4)393-399(1995) 5.Flinn, A.M., and Gennery, A.R.Adenosine deaminase deficiency: A reviewOrphanet J.

2-Aminoimidazole is a potent antibiofilm agent and adjuvant to antimicrobial treatments, disrupting bacterial self-protection mechanisms by inhibiting biofilm formation and genetically-encoded antibiotic resistance traits. Additionally, 2-Aminoimidazole acts as a weak noncompetitive inhibitor of human arginase I, with a Ki value of 3.6 mM[1][2][3].

Cannabidiol hydroxyquinone (HU-331) is potentially an active metabolite of cannabidiol that could play a role in inducing apoptosis. It functions by inhibiting the ATPase activity of topoisomerase IIα through a noncompetitive mechanism.

Halichondrin B, sourced from the sponge Halichondria okadai, serves as a noncompetitive inhibitor of Vinca-alkaloid binding to tubulin, with an IC 50 for tubulin polymerization ranging from 1.2-1.4 μM, and exhibits anti-tumor activity [1].

Picrotoxinin is a blocker of chloride channel and a noncompetitive antagonist of GABAA with an IC50 of 1.15 μM for α1β2γ2L GABAA. Picrotoxinin shows convulsant properties.
