Salts containing different amino acids: four types of salts with the sulfate anion

چکیده

In the present paper, we report crystal structures of four types ([A(1)H][A(2)H]Y, [A(1)H]3[A(2)H]Y2, A(1)H[A(2)H···A(2)]Y, and A(1)H[A(1)H···A(2)]Y) mixed salts containing sulfate anion (Y = SO42−) amino acids A, i.e., sarcosine (Sar), dimethylglycine (DMG), betaine (Bet), β-alanine (β-Ala), l-proline (l-Pro): (β-AlaH)(DMGH)SO4·2H2O (I), (β-AlaH)(BetH)SO4 (II), (β-AlaH)(l-ProH)SO4 (III), (BetH)(l-ProH)SO4 (IV), (SarH)3(l-ProH)(SO4)2 (V), (β-AlaH)(l-ProH···l-Pro)SO4 (VI), (β-AlaH)(β-AlaH···DMG)SO4 (VII). The O···O distances in dimeric cations (l-ProH···l-Pro) (β-AlaH···DMG) are 2.450(3) 2.5295(12) Å (VI) (VII), respectively. Crystal structure determinations (II) at 100 K (P21/n), 200 (Pnma), 250 room temperature (Pnma) revealed a structural phase transition interval between K.

Preparation and Characterization of Amino Acids-Based Trimethoprim Salts

Trimethoprim (TMP) is a dihydrofolate reductase (DHFR) inhibitor which prevents the conversion of dihydrofolic acid into tetrahydrofolic acid, resulting in the depletion of the latter and leading to bacterial death. Oral bioavailability of TMP is hindered by both its low solubility and low permeability. This study aims to prepare novel salts of TMP using anionic amino acids; aspartic and glutam...

Complex Salts of Amino Acids and Peptides I. Metal Complex Salts of Glycine and Their Specificity by Max Bergmann

The mixtures of amino acids resulting from the hydrolysis of proteins and similar substances may be analyzed by the well known methods of Kossel and Kutscher, Fischer, Dakin, Van Slyke, Osborne, Vickery, and others. However, after hydrolyzing proteins with enzymes, one is faced with the difficult problem of determining the resultant amino acids and peptides without t,he occurrence of secondary ...
