Sheng, Tao; Kong, Mengmeng; Wang, Yujie; Wu, HuiJun; Gu, Qin; Chuang, Anita Shyying; Li, Shengkun; Gao, Xuewen published their research in European Journal of Medicinal Chemistry in 2021. The article was titled 《Discovery and preliminary mechanism of 1-carbamoyl β-carbolines as new antifungal candidates》.Application of 7524-52-9 The article contains the following contents:

Various 1-substituted β-carbolines I (R1 = CH3, C6H5, 4-BrC6H4, etc.), II (R2 = C6H5, CONH2, CONHC6H5, etc.), III (R3 = Me, Ph, OH, etc.) and IV (R4 = Me, Ph, 2-pyridyl, etc.) were synthesized from com. inexpensive tryptophan and demonstrated significant in vitro antifungal activity against G. graminis. Significantly, compound II (R2 = CONH2) (EC50 = 0.45μM) with carboxamide at 1-position displayed the best efficacy and nearly 20 folds enhancement in antifungal potential compared to Silthiopham (EC50 = 8.95μM). Moreover, compounds 4,9-dihydro-3H-pyrido[3,4-b]indole-1-carboxamide, 9H-pyrido [3,4-b]indole-1-carboxamide, and II (R2 = CO2Me) exhibited excellent in vitro antifungal activities and in vivo protective and curative activities against B. cinerea and F. graminearum. Preliminary mechanism studies revealed that compound II (R2 = CONH2) caused reactive oxygen species accumulation, cell membrane destruction, and deregulation of histone acetylation. These findings indicated that 1-carbamoyl β-carbolines I, II, III and IV can be selected as a promising model for the discovery of novel and broad-spectrum fungicide candidates.H-Trp-OMe.HCl(cas: 7524-52-9Application of 7524-52-9) was used in this study.

The article was titled 《A new class of α-ketoamide derivatives with potent anticancer and anti-SARS-CoV-2 activities》, and you may find the article in European Journal of Medicinal Chemistry.Related Products of 7524-52-9 The information in the text is summarized as follows:

Inhibitors of the proteasome have been extensively studied for their applications in the treatment of human diseases such as hematol. malignancies, autoimmune disorders, and viral infections. Many of the proteasome inhibitors reported in the literature target the non-primed site of proteasome′s substrate binding pocket. In this study, we designed, synthesized and characterized a series of novel α-keto phenylamide derivatives aimed at both the primed and non-primed sites of the proteasome. In these derivatives, different substituted Ph groups at the head group targeting the primed site were incorporated in order to investigate their structure-activity relationship and optimize the potency of α-keto phenylamides. In addition, the biol. effects of modifications at the cap moiety, P1, P2 and P3 side chain positions were explored. Many derivatives displayed highly potent biol. activities in proteasome inhibition and anticancer activity against a panel of six cancer cell lines, which were further rationalized by mol. modeling analyses. Furthermore, a representative α-ketoamide derivative was tested and found to be active in inhibiting the cellular infection of SARS-CoV-2 which causes the COVID-19 pandemic. These results demonstrate that this new class of α-ketoamide derivatives are potent anticancer agents and provide exptl. evidence of the anti-SARS-CoV-2 effect by one of them, thus suggesting a possible new lead to develop antiviral therapeutics for COVID-19.H-Trp-OMe.HCl(cas: 7524-52-9Related Products of 7524-52-9) was used in this study.

A simple and efficient KI promoted sulfur activation-insertion/de-nitration strategy has been developed for the synthesis of β-carboline C1 tethered 2-acylbenzothiophenes via one-pot assembly of 1-acetyl β-carbolines (an alkaloid based scaffold), 2-nitrobenzaldehydes and elemental sulfur. This expeditious reaction proceeds through the formation of β-carboline linked nitro-chalcones followed by embodiment of elemental sulfur to generate the multifunctional β-carboline linked benzothiophene derivatives The highlighted features of this efficient methodol. are transition metal-free conditions, use of inexpensive and non-toxic catalyst, easy procedure, short reaction time, and broad substrate scope with good yields. The scope of this protocol has been extended for the synthesis of a range of novel compounds with significant diversity. The results came from multiple reactions, including the reaction of H-Trp-OMe.HCl(cas: 7524-52-9Synthetic Route of C12H15ClN2O2)

Kervefors, Gabriella; Kersting, Leonard; Olofsson, Berit published their research in Chemistry – A European Journal in 2021. The article was titled 《Transition metal-free N-arylation of amino acid esters with diaryliodonium salts》.Synthetic Route of C12H15ClN2O2 The article contains the following contents:

A transition metal-free approach for the N-arylation of amino acid derivatives has been developed. Key to this method is the use of unsym. diaryliodonium salts with anisyl ligands, which proved important to obtain high chemoselectivity and yields. The scope includes the transfer of both electron deficient, electron rich and sterically hindered aryl groups with a variety of different functional groups. Furthermore, a cyclic diaryliodonium salt was successfully employed in the arylation. The N-arylated products were obtained with retained enantiomeric excess.

The article was titled 《Synthesis of C-mannosylated glycopeptides enabled by Ni-catalyzed photoreductive cross-coupling reactions》, and you may find the article in Journal of the American Chemical Society.Reference of H-Trp-OMe.HCl The information in the text is summarized as follows:

The biol. functions of tryptophan C-mannosylation are poorly understood, in part, due to a dearth of methods for preparing pure glycopeptides and glycoproteins with this modification. To address this issue, efficient and scalable methods are required for installing this protein modification. Here, we describe unique Ni-catalyzed cross-coupling conditions that utilize photocatalysis or a Hantzsch ester photoreductant to couple glycosyl halides with (hetero)aryl bromides, thereby enabling the α-C-mannosylation of 2-bromo-tryptophan, peptides thereof, and (hetero)aryl bromides more generally. We also report that 2-(α-D-mannopyranosyl)-L-tryptophan undergoes facile anomerization in the presence of acid: something that must be considered when preparing and handling peptides with this modification. These developments enabled the first automated solid-phase peptide syntheses of C-mannosylated glycopeptides, which we used to map the epitope of an antibody, as well as providing the first verified synthesis of Carmo-HrTH-I, a C-mannosylated insect hormone. To complement this approach, we also performed late-stage tryptophan C-mannosylation on a diverse array of peptides, demonstrating the broad scope and utility of this methodol. for preparing glycopeptides.H-Trp-OMe.HCl(cas: 7524-52-9Reference of H-Trp-OMe.HCl) was used in this study.

《Design, synthesis and bio-evaluation of C-1 alkylated tetrahydro-β-carboline derivatives as novel antifungal lead compounds》 was published in Bioorganic & Medicinal Chemistry Letters in 2020. These research results belong to Singh, Rahul; Jaisingh, Aanchal; Maurya, Indresh K.; Salunke, Deepak B.. Product Details of 7524-52-9 The article mentions the following:

The field of antifungal agent has become static and development of resistance by the pathogen as well as limited clin. efficacy of marketed drugs demand the constant development of new antifungals. The presence of hydrocarbon chain of specific length linked with various different heterocycles was found to be an important structural feature in various antifungal lead compounds Based on the prominent antimicrobial activity of β-carboline derivatives, a set of C1 alkylated tetrahydro-β-carboline derivatives were proposed to be active against fungi. To validate and confirm the role of suitable alkyl chains linked to a β-carboline scaffold, few related analogs having C1 aryl substituents were also synthesized in one step via classic Pictet-Spengler reaction. The synthesized library was evaluated for its antifungal activity against C. albicans, C. krusei, C. parapsilosis, C. kefyr, C. glabrata, C. tropicalis and C. neoformans. One of the library members I, with n-alkyl chain of eight carbons exhibited potent antifungal activity against C. glabrata and C. kefyr. The lead compound, being selectively toxic also demonstrated prominent synergy enhancing the potency of antifungal drugs up to 10-fold. The time kill kinetic studies confirmed the efficacy of compound I, where the results obtained were comparable to that of Amp B. FE-SEM anal. revealed the increased asymmetry, disintegration and roughness of cell surface which could be because of the possible interaction of compound I at membrane level or interference in cell wall structure. Apoptosis/necrosis detection assay confirmed the significant apoptotic activity in C. glabrata cells after I treatment which was responsible for the rapid killing of C. glabrata cells.
