Testosterone enanthate
CAS:Produto ControladoTestosterone enanthate is a long-acting ester of the natural hormone testosterone. It is used to treat male hypogonadism, as well as for female infertility. Testosterone enanthate has been found to be effective in maintaining physiological levels of testosterone in the blood and in increasing follicular growth, body mass index, and bone density.

CAS:2,6-Dimethylnaphthalene is a methylating agent that reacts with carbonyl groups to form methyl esters. It has been shown to be effective in the production of dimethylnaphthalene from 2,6-dimethylnaphthalene. The mechanism of the reaction is thought to involve acid catalysis and hydrogen bonding. The activation energies for this process are estimated at -3.4 kcal/mol and -0.8 kcal/mol, respectively for the forward and reverse reactions. The kinetic parameters for this reaction have been determined by fitting the data to a first order rate equation, yielding a rate constant of 4.5x10^-3 s^(-1) and an equilibrium constant of 1.27x10^-7 M^(-2). A flow system has been used in an attempt to optimise the reaction conditions: hydrochloric acid was added as a catalyst and increased the yield of dimethylnaphthalene by 10Fórmula:C12H12Cor e Forma:PowderPeso molecular:156.22 g/molN-Methyl-L-tyrosine - Combretum collinum
CAS:N-Methyl-L-tyrosine is a molecule that has been studied as a potential treatment for Parkinson's disease. It is chemically related to the amino acid tyrosine and also shares some of its biological properties. N-Methyl-L-tyrosine inhibits the uptake of dopamine by dopamine transporters in cells, which reduces the symptoms of Parkinson's disease. The alkynyl group present in this molecule helps to improve the drug's binding affinity with proctolin, which is a substrate for proton pump inhibitors, and can be used to treat gastrointestinal problems. The clinical use of N-Methyl-L-tyrosine is limited due to its low oral bioavailability; however, it may be effective when administered intravenously or intramuscularly.Fórmula:C10H13NO3Pureza:Min. 95%Cor e Forma:White PowderPeso molecular:195.22 g/molN-(3-Methylbutyl)adenosine
CAS:3-Methylbutyl adenosine is a nucleoside that is a component of the adenosine phosphates, which are important for protein synthesis. 3-Methylbutyl adenosine is found in plants and has been shown to be synthesized by the oxidative deamination of pyridinium. This compound has been shown to have anticancer activity, but it also induces hemolysis. The reaction products of 3-methylbutyl adenosine with ferroptosis and cancer cells have not yet been determined.Fórmula:C15H23N5O4Pureza:Min. 95%Cor e Forma:White PowderPeso molecular:337.37 g/mol
