Formula:C28H48OPurity:Min. 95%Molecular weight:400.68 g/mol4-Chlorocinnamic acid
CAS:4-Chlorocinnamic acid is a malonic acid derivative and one of the cinnamic acid derivatives that has been shown to inhibit many chemical reactions. It inhibits the production of tyrosinase, which is an enzyme that catalyzes the conversion of tyrosinase to 4-hydroxycinnamic acid. 4-Chlorocinnamic acid also inhibits the growth of Candida glabrata in vitro. The effect on candida is due to its ability to inhibit the production of hydroxyl group and aromatic hydrocarbon, both of which are required for candida's survival. 4-Chlorocinnamic acid binds with aryl halide and neutral ph, preventing it from reacting with other substances.

The mode of action of 3,3',4',5,5',8-Hexahydroxyflavone involves its interaction with various cellular pathways and enzymes. Primarily, it is known for its antioxidant properties, where it scavenges free radicals and reactive oxygen species, thereby reducing oxidative stress. Additionally, it may exhibit anti-inflammatory effects by modulating signaling pathways involved in inflammation.
In terms of uses and applications, 3,3',4',5,5',8-Hexahydroxyflavone is primarily explored in scientific research focusing on its potential health benefits. Studies investigate its role in disease prevention, particularly conditions associated with oxidative stress and inflammation, such as cardiovascular diseases and neurodegenerative disorders. While it holds promise in these areas, further research is necessary to fully understand its mechanisms and therapeutic potential.Formula:C15H10O8Purity:Min. 95%Molecular weight:318.24 g/molb-Propiolactone
CAS:Controlled Productb-Propiolactone is a plant extract that is found in soybeans. It has been shown to have antiviral properties and can inhibit the growth of certain viruses. b-Propiolactone binds to the active site of an enzyme called RNA polymerase, which blocks RNA synthesis and inhibits viral replication. This compound has also been shown to inhibit virus replication in vitro assays as well as antibody response against hepatitis B. The biological effects of b-propiolactone are thought to be due to its ability to bind with group p2 protein monoclonal antibodies, which may have implications for the prevention of pandemic influenza.

CAS:Controlled ProductPentazocine lactate is an opioid that binds to the kappa-opioid receptor. It has a low potency and is used as an analgesic. Pentazocine lactate has been shown to be effective in the treatment of eosinophilic fasciitis, which is a rare inflammatory disease of the skin and soft tissue. Side effects for this drug include respiratory depression and sedation, constipation, nausea/vomiting, urinary retention, erythema multiforme, pruritus, erythema nodosum, thrombocytopenia, and fever. Pentazocine lactate may also interact with other drugs such as antidepressants or antipsychotics.
Formula:C19H27NO·C3H6O3Purity:Min. 95%Molecular weight:375.5 g/mol1-(3,4-Methylenedioxyphenyl) 2-nitropropene
CAS:1-(3,4-Methylenedioxyphenyl) 2-nitropropene (1-MPNP) is a phosphatase inhibitor that is active against gram-negative bacteria by inhibiting enterotoxins and chlamydia. 1-MPNP inhibits the activity of tyrosine phosphatases, which are enzymes that play a major role in bacterial virulence. 1-MPNP competitively inhibits the activity of tyrosine phosphatases and prevents them from catalyzing the hydrolysis of polyphosphate substrates. This inhibition leads to an accumulation of polyphosphates in the bacterial cell membrane, which disrupts its permeability and leads to cell death.

Discontinued product1-(3-Chlorophenyl) thiourea
CAS:1-(3-Chlorophenyl) thiourea is a curcumin analog that has been shown to inhibit the epidermal growth factor (EGF) receptor. It is synthesized from 1,2-dichlorobenzene and urea in a two-step process. The anhydrous potassium carbonate is first converted to the potassium salt with an acid chloride. The second step is the reaction of this salt with urea in the presence of excess anhydrous potassium carbonate. This product has been shown to be effective against cancer cells and may be used as a potential anticancer agent for treatment of skin cancer. 1-(3-Chlorophenyl) thiourea inhibits EGF receptor by binding to it and preventing its activation, which prevents cell proliferation and reduces tumor size.
