1999-46-8 Usage

General Description

DL-ALANYL-DL-VALINE is a dipeptide composed of two amino acids, alanine and valine. Both of these amino acids are essential in the human diet and are important for protein synthesis and overall health. Alanine is a non-essential amino acid that plays a key role in glucose metabolism and the immune system, while valine is an essential amino acid that is necessary for muscle metabolism and tissue repair. DL-ALANYL-DL-VALINE is commonly used as a nutritional supplement in sports drinks and protein powders to support muscle growth and recovery. Additionally, it has been shown to have potential therapeutic benefits in the treatment of liver diseases and metabolic disorders.

Check Digit Verification of cas no

The CAS Registry Mumber 1999-46-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,9 and 9 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1999-46:
(6*1)+(5*9)+(4*9)+(3*9)+(2*4)+(1*6)=128
128 % 10 = 8
So 1999-46-8 is a valid CAS Registry Number.

Coupling-Reagent-Free Synthesis of Dipeptides and Tripeptides Using Amino Acid Ionic Liquids

Furukawa, Shinya,Fukuyama, Takahide,Matsui, Akihiro,Kuratsu, Mai,Nakaya, Ryotaro,Ineyama, Takashi,Ueda, Hiroshi,Ryu, Ilhyong

supporting information, p. 11980 - 11983 (2015/08/18)

A general method for the synthesis of dipeptides has been developed, which does not require any coupling reagents. This method is based on the reaction of readily available HCl salts of amino acid methyl esters with tetrabutylphosphonium amino acid ionic liquids. The isolation procedure of stepwise treatment with AcOH is easy to carry out. The method was extended to the synthesis of tripeptide, tyrosyl-glycyl-glycine, present in IMREG-1, also.

A mild method for the cleavage of the 4-picolyloxy group with magnesium under neutral conditions

Zhu, Jianwei,Miao, Wenjun,Bao, Lingling,Ji, Tao,Tang, Guo,Xu, Pengxiang,Zhao, Yufen

supporting information; experimental part, p. 142 - 144 (2012/02/04)

A mild and efficient method for the selective hydrolysis of 4-picolyl esters with magnesium in methanol or water in the presence of other esters and sensitive protecting groups is described. 4-Picolyl aryl ethers and thioethers are also smoothly deprotected to give the corresponding phenols and thiophenols.

Direct asymmetric intermolecular aldol reactions catalyzed by amino acids and small peptides

Cordova, Armando,Zou, Weibiao,Dziedzic, Pawel,Ibrahem, Ismail,Reyes, Efraim,Xu, Yongmei

, p. 5383 - 5397 (2008/02/13)

In nature there are at least nineteen different acyclic amino acids that act as the building blocks of poly-peptides and proteins with different functions. Here we report that α-amino acids, β-amino acids, and chiral amines containing primary amine functions catalyze direct asymmetric intermolecular aldol reactions with high enantio-selectivities. Moreover, the amino acids can be combined into highly modular natural and unusual small peptides that also catalyze direct asymmetric intermolecular aldol reactions with high stereoselectivities, to furnish the corre sponding aldol products with up to > 99% ee. Simple amino acids and small peptides can thus catalyze asymmetric aldol reactions with stereoselectivities matching those of natural enzymes that have evolved over billions of years. A small amount of water accelerates the asymmetric aldol reactions catalyzed by amino acids and small peptides, and also increases their stereoselectivities. Notably, small peptides and amino acid tetrazoles were able to catalyze direct asymmetric aldol reactions with high enantioselectivities in water, while the parent amino acids, in stark contrast, furnished nearly racemic products. These results suggest that the prebiotic oligomerization of amino acids to peptides may plausibly have been a link in the evolution of the homochirality of sugars. The mechanism and stereochemistry of the reactions are also discussed.
