A unified strategy to reverse-prenylated indole alkaloids: total syntheses of preparaherquamide, premalbrancheamide, and (+)-VM-55599

A full account of our studies toward reverse-prenylated indole alkaloids that contain a bicyclo[2.2.2]core is described. A divergent route is reported which has resulted in the synthesis of preparaherquamide, (+)-VM-55599, and premalbrancheamide. An intramolecular Dieckmann cyclization between an enolate and isocyanate was used to forge the bicyclo[2.2.2]diazaoctane core that is characteristic of these molecules. The pentacyclic indole scaffold was constructed through a one-pot Hofmann rearrangement followed by Fischer indole synthesis. The utilization of our previously reported indole peripheral functionalization strategy also led to natural products including malbrancheamides B, C, stephacidin A, notoamides F, I and R, aspergamide B, and waikialoid A. Ultimately, the divergent route that we devised provided access to a wide range of prenylated indole alkaloids that are differently substituted on the cyclic amine core.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 948-65-2. Product Details of 948-65-2.

Design, synthesis, antifungal activity, and QM/MM docking study of two azole derivatives with indole ring

Systemic candidiasis is a major health issue for immunocompromised individuals due to the increase in drug-resistance among Candida spp., which are prevalent pathogenic fungi responsible for many types of fungal infections. Azoles are among the most preferred antifungal class for systemic candidiasis with broad antifungal spectrum and systemic availability. In this study, we synthesized and tested antifungal effects of two new indole derivatives to investigate the impact of indole on the activity of azole antifungal compounds and to find potent derivatives against Candida spp. including resistant strains and biofilms. 1-(4-Chlorophenyl)-2-(1H-imidazol-1-yl)ethanol 1H-indole-2-carboxylate (4a) showed excellent antifungal profile with several times more potent activity against the tested species including a fluconazole-resistant C. tropicalis isolate. The minimum inhibitory concentration (MIC) of 4a was 0.03125 mu g/ml against C. albicans, which was 0.5 mu g/ml for fluconazole. The compound also showed promising biofilm inhibitory effect compared to amphotericin B. The importance of indole was demonstrated through molecular docking studies with the structure of C. albicans CYP51, the established target of azole antifungals, using different protocols. QM/MM docking approach yielded excellent results and accuracy, especially regarding metal interactions. As a result, indole could be a very useful fragment to design new and highly potent antifungal compounds in azole structure.

The Selective N-Functionalization of Indoles via aza-Michael Addition in the Ligand Sphere of a Chiral Nickel(II) Complex: Asymmetric Synthesis of (S)-1H-Indole-Alanine Derivatives

The selective addition of electrophilic C=C double bonds to the N-H bond of indoles is a challenging task due to the high nucleophilicity of indoles at their C3-position. Herein, we report the successful selective intermolecular N-functionalization of various indoles via aza-Michael addition of C=C double bond of a dehydroalanine Schiff base, which takes place in the ligand sphere of a chiral Ni-II complex in the presence of sodium hydride. The resulting hydroaminated Ni-II complexes were isolated in 55-82 % yields with excellent diastereoselectivity (dr > 99:1) (8 examples). And the actual products of interest, namely (S)-2-amino-3-(1H-indol-1-yl)propanoic acids, were subsequently released from the Ni-II complexes via aqueous HCl treatment of the Ni-II complexes and isolated with excellent enantioselectivity (> 99 % ee). The chiral auxiliary [(S)-BPB = (S)-2-(N-benzylprolyl)aminobenzophenone] and Ni-II ions can be easily recovered after the acidic complex cleavage step and reused for the synthesis of the starting Ni-II complex. Moreover, the indole ‘ s preference for nucleophilic attack via its N1- over its C3-position was rationalized by DFT calculations.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 7300-91-6, in my other articles.

Palladium-catalyzed enantioselective decarboxylative allylic alkylation of fully substituted N-acyl indole-derived enol carbonates

The first enantioselective palladium-catalyzed decarboxylative allylic alkylation of fully substituted N-acyl indole-derived enol carbonates forming acyclic all-carbon quaternary stereocenters is reported. Excellent yields up to 99% and enantioselectivities up to 98% ee are obtained through the use of a new electron-deficient phosphinoxazoline (PHOX) ligand. Control of substrate enolate geometry is crucial for high selectivity. The obtained a-quaternary N-acyl indoles are formal ester equivalents, and represent a useful handle for further synthetic transformations.

Widely targeted metabolic analysis revealed the changed pigmentation and bioactive compounds in the ripening Berchemia floribunda (Wall.) Brongn. fruit

Berchemia plants were important materials for Chinese traditional medicines due to their special secondary metabolites. Unlike the root, stem and leaf tissues, Berchemia floribunda (Wall.) Brongn. fruit was lacked of systematic metabolic investigation. Biochemical analysis found that the total flavonoid and total phenolic content of Berchemia fruit pulp showed a peak value at red ripe stage, and then decreased, but the total anthocyanin content sharply increased along with the coloration. By widely targeted metabolomic analysis, 644 metabolites were identified and categorized into 23 groups mainly including flavonoid, organic acids, amino acids, lipids, phenylpropanoid, nucleotides, alkaloids, carbohydrates, alcohols, anthocyanins & proanthocyanidins, vitamins, terpenes, polyphenols, phenolamides, quinones, indole derivatives, and sterides. Among them, 111 metabolites and 123 metabolites respectively showed up- and down-regulation from break stage to full mature. KEGG enrichment analysis indicated that active secondary metabolism such as biosynthesis of phenylpropanoids, flavonoid, and alkaloids happened during Berchemia fruit ripening. More importantly, Cyanidin-3-O-galactoside and other 3 cyanidins were found to be the predominant pigments in mature Berchemia fruit and increased cyanidins and pelargonidins but decreased anthocyanins might be contributed to the purple pigmentation of Berchemia fruit. Interestingly, 29 pharmaceutical compounds previously reported in other Berchemia tissues were also detected in ripening Berchemia fruit pulp: 8 flavonoid, 2 quinones & sucrose showed up-regulated accumulation while 6 polyphenols, 5 flavonoid, 3 phenylpropanoid, 2 organic acids, 1 quinones and beta-sitosterol showed down-regulated accumulation In conclusion, our first comprehensive metabolic fingerprint will promote the further study of B. floribunda fruit and its medical and food application.

General synthesis of unnatural 4-, 5-, 6-, and 7-bromo-D-tryptophans by means of a regioselective indole alkylation

A general two-step approach to enantiopure bromotryptophans from unprotected bromoindoles has been developed. Indole nucleophiles prepared with MeMgCl in the presence of CuCl reacted with cyclic sulfamidates derived from enantiopure D-serine to form 4-, 5-, 6-, or 7-bromo-D-tryptophan and some other halogenated tryptophans in moderate yields but with complete regioselectivity. The bromotryptophan derivatives were deprotected using mild conditions. (C) 2020 Elsevier Ltd. All rights reserved.

Deprotection of N-tert-Butoxycarbonyl (Boc) Protected Functionalized Heteroarenes via Addition-Elimination with 3-Methoxypropylamine

Continued pursuit of functionalized soft-N-donor complexant scaffolds with favorable solubility and kinetics profiles applicable for the separation of the trivalent minor actinides from the lanthanides has attracted significant interest over the last three decades. Recent work from this laboratory resulted in the production of various N-Boc protected [1,2,4]triazinyl-pyridin-2-yl indole Lewis basic procomplexants which necessitated the removal of the indole N-Boc protecting group prior to evaluation of complexant efficacy in separations assays. Traditional deprotection strategies involving trifluoroacetic and other protic and Lewis acids proved unsuccessful in removal of the recalcitrant indole-N-Boc protecting group necessitating the development of a new strategy for deprotection of this complexant class. A serendipitous result facilitated utilization of 3-methoxypropylamine as a mild deprotecting agent for various N-Boc protected heteroarenes via a proposed addition-elimination mechanism. Method development, application to various heteroarenes including indoles, 1,2-indazoles, 1,2-pyrazoles, and related derivatives, a ten-fold scale-up reaction, and experimental evaluation of a preliminary mechanistic hypothesis are reported herein.

In silico evaluation of isatin-based derivatives with RNA-dependent RNA polymerase of the novel coronavirus SARS-CoV-2

Isatin (1H-indole-2,3-dione)-containing compounds have been shown to possess several remarkable biological activities. We had previously explored a few isatin-based imidazole derivatives for their predicted dual activity against both inflammation and cancer. We explored 47 different isatin-based derivatives (IBDs) for other potential biological activities using in silico tools and found them to possess anti-viral activity. Using AutoDock tools, the binding site, binding energy, inhibitory constant/K (i) and receptor-ligand interactions for each of the compounds were analyzed against SARS-CoV-2 RNA-dependent RNA polymerase (RdRp). The partition coefficient (logP) values were predicted using MedChem Designer tool. Based on the best K (i), binding energy and the ideal range of logP (between 1.0 and 3.0), 10 out of total 47 compounds were deemed to be prospective RdRp inhibitors. Some of these compounds gave better K (i), binding energy and logP values when compared to standard RdRp inhibitors, such as remdesivir (REM) (K (i) = 15.61 mu M, logP = 2.2; binding energy = -6.95), a clinically approved RdRp inhibitor and nine other RdRp inhibitors. The results showed that the 10 selected IBDs could be further explored. Molecular dynamics simulations (MDSs) showed that the selected RdRp-IBD complexes were highly stable compared to the native RdRp and RdRp-REM complex during 100 ns time periods. DFT studies were performed for the compounds 16a, 24a, 28a, 38a and 40a, to evaluate the charge transfer mechanism for the interactions between the IBDs and the RdRp residues. Among these, ADME profiling revealed that 28a is a possible lead compound which can be explored further for anti-RdRp activity in vitro. Communicated by Ramaswamy H. Sarma
