In 2017,Matsumoto, Shoji; Moteki, Jun; Ito, Yuji; Akazome, Motohiro published 《Relationship between mechanochromic behavior and crystal structures in donor-π-acceptor compounds consisted of aromatic rings with ester moiety as an acceptor》.Tetrahedron Letters published the findings.Category: esters-buliding-blocks The information in the text is summarized as follows:

The authors studied the mechanochromic behavior of donor-π-acceptor compounds which consisted of diphenylaminophenylacetylene as a donor-π moiety and (hetero)aromatic ring bearing ester as an acceptor. The compounds with dicyanobenzoic ester gave the bathochromic shift by grinding, whereas the compounds consisting of the ester with benzene, imidazole, and thiazole rings showed the hypsochromic shift. From single-crystal x-ray anal., the authors revealed that the compound with bathochromic shift gave the herringbone alignment with H-aggregate-like π-stacking in the crystal structure. On the contrary, the compounds with hypsochromic shift showed the structure with the alignment of long axis of the mol. in crystal structure. In the experiment, the researchers used Ethyl 2-amino-2-thioxoacetate(cas: 16982-21-1Category: esters-buliding-blocks)

And the article was published in Bioorganic Chemistry in 2019. Product Details of 16982-21-1 The author mentioned the following in the article:

In this work, an enlarged series of 1,2,4-triazolo[4,3-a]pyrazin-3-ones was designed to target the human (h) A2A adenosine receptor (AR) or both hA1 and hA2A ARs. The novel 8-amino-1,2,4-triazolopyrazin-3-one derivatives 1-25 featured a Ph or a benzyl pendant at position 2 while different aryl/heteroaryl substituents were placed at position 6. Two compounds (8(I) and 10(II)) endowed with high affinity (Ki = 7.2 and 10.6 nM) and a complete selectivity for the hA2A AR were identified. Moreover, several derivatives possessed nanomolar affinity for both hA1 and hA2A ARs (both Ki < 20 nM) and different degrees of selectivity vs. the hA3 AR. Two selected compounds (II and 25(III)) demonstrated ability in preventing β-amyloid peptide (25-35)-induced neurotoxicity in SH-SY5Y cells. Results of docking studies at the hA2A and hA1 AR crystal structures helped us to rationalize the observed affinity data and to highlight that the steric hindrance of the substituents at the 2- and 6-position of the bicyclic core affects the binding mode in the receptor cavity.

In 2016,Wang, Guangcheng; He, Dianxiong; Li, Xin; Li, Juan; Peng, Zhiyun published 《Design, synthesis and biological evaluation of novel coumarin thiazole derivatives as α-glucosidase inhibitors》.Bioorganic Chemistry published the findings.Category: esters-buliding-blocks The information in the text is summarized as follows:

A new series of coumarin thiazole derivatives 7a-7t were synthesized, characterized by 1H NMR, 13C NMR and element anal., evaluated for their α-glucosidase inhibitory activity. The majority of the screened compounds displayed potent inhibitory activities with IC50 values in the range of 6.24 ± 0.07-81.69 ± 0.39 μM, when compared to the standard acarbose (IC50 = 43.26 ± 0.19 μM). Structure-activity relationship (SAR) studies suggest that the pattern of substitution in the Ph ring is closely related to the biol. activity of this class of compounds Among all the tested mols., compound 7e (IC50 = 6.24 ± 0.07 μM) was found to be the most active compound in the library of coumarin thiazole derivatives Enzyme kinetic studies showed that compound 7e is a non-competitive inhibitor with a Ki of 6.86 μM. Furthermore, the binding interactions of compound 7e with the active site of α-glucosidase were confirmed through mol. docking. This study has identified a new class of potent α-glucosidase inhibitors for further investigation.

In 2011,Bacchi, Alessia; Carcelli, Mauro; Compari, Carlotta; Fisicaro, Emilia; Pala, Nicolino; Rispoli, Gabriele; Rogolino, Dominga; Sanchez, Tino W.; Sechi, Mario; Neamati, Nouri published 《HIV-1 IN Strand Transfer Chelating Inhibitors: A Focus on Metal Binding》.Molecular Pharmaceutics published the findings.HPLC of Formula: 16982-21-1 The information in the text is summarized as follows:

Most active and selective strand transfer HIV-1 integrase (IN) inhibitors contain chelating functional groups that are crucial feature for the inhibition of the catalytic activities of the enzyme. In particular, diketo acids and their derivatives can coordinate one or two metal ions within the catalytic core of the enzyme. The present work is intended as a contribution to elucidate the mechanism of action of the HIV-IN inhibitors by studying the coordinative features of H2L1 (L-708,906), an important member of the diketo acids family of inhibitors, and H2L2, a model for S-1360, another potent IN inhibitor. Magnesium(II) and manganese(II) complexes of H2L1 and H2L2 were isolated and fully characterized in solution and in the solid state. The crystal structures of the manganese complex [Mn(HL2)2(CH3OH)2]·2CH3OH were solved by x-ray diffraction anal. Moreover, the speciation models for H2L2 with magnesium(II) and manganese(II) ions were performed and the formation constants of the complexes were measured. M(HL2)2 (M = Mg2+, Mn2+) was the most abundant species in solution at physiol. pH. All the synthesized compounds were tested for their anti-IN activity, showing good results both for the ligand and the corresponding complexes. From anal. of the speciation models and of the biol. data we can conclude that coordination of both metal cofactors could not be strictly necessary and that inhibitors can act as complexes and not only as free ligands.

Ethyl 2-amino-2-thioxoacetate(cas: 16982-21-1) belongs to anime. Nitrous acid converts secondary amines (aliphatic or aromatic) to N-nitroso compounds (nitrosamines): R2NH + HNO2 → R2N―NO. Some nitrosamines are potent cancer-inducing substances, and their possible formation is a serious consideration when nitrites, which are salts of nitrous acid, are present in foods or pharmaceutical preparations. Tertiary amines give rise to nitrosamines more slowly; an alkyl group is eliminated as an aldehyde or ketone, along with nitrous oxide, N2O.HPLC of Formula: 16982-21-1

Product Details of 16982-21-1In 2019 ,《Enzymatic and Site-Specific Ligation of Minimal-Size Tetrazines and Triazines to Proteins for Bioconjugation and Live-Cell Imaging》 was published in Bioconjugate Chemistry. The article was written by Baalmann, Mathis; Ziegler, Michael J.; Werther, Philipp; Wilhelm, Jonas; Wombacher, Richard. The article contains the following contents:

Diels-Alder reactions with inverse electron demand (DAinv) have emerged as an indispensable tool for bioorthogonal labeling and the manipulation of biomols. In this context, reactions between tetrazines and strained dienophiles have received attention because of high reaction rates. Current methods for the DAinv-mediated functionalization of proteins suffer from slow reactivity, impaired stability, isomerization, or elimination of the incorporated strained dienophiles. We report here a versatile platform for the posttranslational, highly selective, and quant. modification of proteins with stable dienes. New synthetic access to minimal size tetrazine and triazine derivatives enabled us to synthesize tailored diene substrates for the lipoic acid protein ligase A (LplA) from Escherichia coli, which we employ for the rapid, mild, and quant. bioconjugation of proteins by DAinv. The presented method benefits from the minimal tag size for LplA recognition and can be applied to proteins from any source organism. We demonstrate its broad suitability by site-specific in vitro protein labeling and live cell labeling for fluorescence microscopy. With this work we expand the scope of DAinv bioorthogonal chem. for site-specific protein labeling, providing addnl. exptl. flexibility for preparing well-defined bioconjugates and addressing biol. questions in complex biol. environments.

Oral delivery of previously disclosed purine and benzimidazole fructose-1,6-bisphosphatase (FBPase) inhibitors via prodrugs failed, which was likely due to their high mol. weight (>600). Therefore, a smaller scaffold was desired, and a series of phosphonic acid-containing thiazoles, which exhibited high potency against human liver FBPase (IC50 of 10-30 nM) and high selectivity relative to other 5′-adenosinemonophosphate (AMP)-binding enzymes, were discovered using a structure-guided drug design approach. The initial lead compound I produced profound glucose lowering in rodent models of type 2 diabetes mellitus (T2DM) after parenteral administration. Various phosphonate prodrugs were explored without success, until a novel phosphonic diamide prodrug approach was implemented, which delivered compound I with good oral bioavailability (OBAV) (22-47%). Extensive lead optimization of both the thiazole FBPase inhibitors and their prodrugs culminated in the discovery of compound II (MB06322) as the first oral FBPase inhibitor advancing to human clin. trials as a potential treatment for T2DM.Ethyl 2-amino-2-thioxoacetate(cas: 16982-21-1Category: esters-buliding-blocks) was used in this study.
