Structural Basis for the Inhibition of Mycobacterial MmpL3 by NITD-349 and SPIRO

Novel antitubercular agents are urgently needed to combat the emergence of global drug resistance to human tuberculosis. Mycobacterial membrane protein Large 3 (MmpL3) is a promising drug target because its activity is essential and required for cell-wall biosynthesis. Several classes of MmpL3 inhibitors have been developed against Mycobacterium tuberculosis (Mtb) with potent anti-tuberculosis activity. These include the drug candidate SQ109, which has progressed to phase IIb/III clinical trials. Here, we have determined the crystal structures of MmpL3 in complex with NITD-349 and SPIRO. Both inhibitors bind deep in the central channel of transmembrane domain and cause conformational changes to the protein. The amide nitrogen and indole nitrogen of NITD-349 and the piperidine nitrogen of SPIRO interact and clamp Asp645. Structural analysis of the two structures reveals that these inhibitors target the proton relay pathway to block the activity of MmpL3. The findings presented here enrich our understanding of the binding modes of MmpL3 inhibitors and provide directions to enable further rational drug design targeting MmpL3. (C) 2020 Elsevier Ltd.

New thiazolidine-2,4-dione derivatives combined with organometallic ferrocene: Synthesis, structure and antiparasitic activity

Favourable physicochemical properties of an organometallic ferrocene and antiplasmodial potency of compounds containing the thiazolidine-2,4-dione framework (TZD-4) prompted us to explore compounds containing both the thiazolidine-2,4-dione core and the ferrocenyl unit with the primary aim of identifying compounds with promising antiprotozoal activities. Thus, a new series of rationally designed ferrocene-based thiazolidine-2,4-dione derivatives, containing a selection of secondary cyclic amines, was synthesised and fully characterised using standard spectroscopic techniques. The resulting compounds were screened for their antiplasmodial and antitrypanosomal activities against both the chloroquine-resistant (Dd2) strain of Plasmodium falciparum and the Nagana Trypanosoma brucei brucei 427. The general trend that emerged indicated that the target compounds were more selective towards T. b. brucei compared to the P. falciparum parasite. Moreover, the analogues bearing methylpiperazine (8a) and piperidine (8b) rings were more active against T. b. brucei compared to hit compound TZD-4. Except compound 8b, which appeared promising, none of the synthesised compounds showed better activity than TZD-4 against the P. falciparum parasite. All the synthesised compounds were non-toxic and often showed >90% viability of the HeLa cell line screened.

Arynes as Radical Acceptors: TEMPO-Mediated Cascades Comprising Addition, Cyclization, and Trapping

The application of arynes as radical acceptors is described. The stable radical TEMPO (2,2,6,6-tetramethyl piperidine 1-oxyl) is shown to add to various ortho-substituted benzynes generating the corresponding aryl radicals which engage in 5-exo or 6-endo cyclizations. The cyclized radicals are eventually trapped by TEMPO. The introduced method provides ready access to various dihydrobenzofurans, oxindoles, and sultones by a conceptually novel approach.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 188111-79-7 is helpful to your research. SDS of cas: 188111-79-7.

Discovery of MK-8282 as a Potent G-Protein-Coupled Receptor 119 Agonist for the Treatment of Type 2 Diabetes

The ever-growing prevalence of type 2 diabetes in the world has necessitated an urgent need for multiple orally effective agents that can regulate glucose homeostasis with a concurrent reduction in body weight. G-Protein coupled receptor 119 (GPR119) is a GPCR target at which agonists have demonstrated glucose-dependent insulin secretion and shows beneficial effects on glycemic control. Herein, we describe our efforts leading to the identification of a potent, oral GPR-119 agonist, MK-8282, which shows improved glucose tolerance in multiple animal models and has excellent off-target profile. The key design elements in the compounds involved a combination of a fluoro-pyrimidine and a conformationally constrained bridged piperidine to impart good potency and efficacy.

Unusual Synthesis of Triosmium Carbene Clusters by Tandem Activation of Chlorohydrocarbons and Heterocyclic Amines

Reactions of the [Os3H2(CO)(10)] cluster complex (1) with six-membered heterocyclic amines (morpholine, thiomorpholine, piperidine) and halohydrocarbons (CH2Cl2, ClHC=CHCl, CH2=CCl2) at similar to 25 degrees C have been studied. Two main types of products are formed in all studied reactions. One product is carbene cluster [Os-3(mu-H)(mu-Cl){eta(1)-C(CH3)N(CH2CH2)(2)X}(CO)(9)] (X=O, S, CH2) (3, 3 a and 3 b). Second product is cluster containing enamine ligand [Os-3(mu-H){mu-CH=CHN(C2CH2)(2)X)}(2)(CO)(10)] (X=O, S, CH2) (2, 2 a and 2 b). The carbene ligand is assembled on a cluster, from three organic molecules, thus representing the first example of carbene ligands formed in this way. Clusters with carbene ligand exist as two stable isomers (rotamers hindered towards the Os-C bond), as confirmed by NMR studies and conformational analysis. We have found that in reactions of cluster 1 with acyclic amines containing an oxygen atom in gamma-position (likely morpholine in CH2Cl2), only complexes with bridging enamine ligands are formed. Compounds 2 a, 2 b, 3 and 3 b are characterized by single-crystal X-ray diffraction.

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 188111-79-7, in my other articles.

Design of cationic amphiphiles for generating self-assembled soft nanostructures, micelles and hydrogels

Design of amphiphiles to develop robust self-assembled soft nanomaterials, such as micelles and hydrogels is an interesting subject. A series of cationic amphiphilic compounds were synthesized comprising 1-ethoxy (3-pentadecyl) benzene as the hydrophobic tail. The second carbon of ethoxy was linked to quaternary head groups (trimethyl ammonium bromide (PEA), triethyl ammonium bromide (PETE), pyridinium bromide (PEPy),N-methyl morpholino bromide (PENM),N-methyl piperidine bromide (PENP)). Inclusion of benzene ring leads to a significant decrease in critical micellar concentration (CMC) as compared to other cationic surfactants, such as cetyl trimethyl ammonium bromide (CTAB). Interestingly, at higher concentration, these cationic amphiphiles were forming soft hydrogels with critical gelation concentration (CGC) from 3 to 10% (w/v). The small-angle X-ray scattering (SAXS) analysis of xerogel revealed the formation of self-assembled lamellar patterns of molecules. Further, the morphology of xerogels were also seen under a scanning electron microscope (SEM) which correlates with SAXS data. The SAXS and SEM data confirms the formation of worm-like micellar structures and entangle themselves to form a hydrogel. The cytotoxicity assay was done on HDFA, HeLa and HEK cell lines, haemolysis assay showed better haemocompatibility than CTAB. The synthesized surfactants exhibited up to 3-fold higher solubilization capability against hydrophobic molecules than CTAB.

Cyclodepsipeptide Natural Products Apratoxins A and C and Their Analogs

In this study, the total syntheses of apratoxins A and C and their analogs were carried out. Apratoxins A and C and their oxazoline analogs exhibited potent cytotoxicities against cancer cells as well as similar 3D structures in solution as analyzed by a distance geometry method. The oxazoline analogs were slightly less, but highly, potent as they exhibited similar conformations as their parent compounds. As the MoCys moiety possibly induced severe toxicity owing to the ability of a Michael acceptor and instability of the thiazoline ring under acidic and basic conditions, MoCys and MeAla-MeIle were substituted by other simple amino acids. In addition, the combinatorial synthesis of these mimetics was carried out by the split and mix method with solid-phase peptide synthesis and solution-phase macrolactamization in parallel. Apratoxin M7 in which MoCys was replaced by piperidine-4-carboxylic acid was found to exhibit a conformation similar to that of apratoxin A, and indicated moderate activity. Based on apratoxin M7, the further optimization of the Tyr(Me)-MeAla-MeIle tripeptide led to the discovery of apratoxin M16 (Bph/Tyr(Me)), which is as potent as apratoxin A. The growth inhibitory activity of apratoxin A and apratoxin M16 against 10 cancer cell lines was comparable, suggesting that the target of apratoxin M16 should be the same as that of apratoxin A.

Application of a screening method for fentanyl and its analogues using UHPLC-QTOF-MS with data-independent acquisition (DIA) in MSE mode and retrospective analysis of authentic forensic blood samples

The steady appearance of new fentanyl analogues and the associated overdose deaths require the development of sensitive screening approaches to detect these compounds in biological samples and seizures. We developed a targeted screening method to detect 50 4-anilidopiperidine-related fentanyl analogues in whole blood using ultra-high performance liquid chromatography quadrupole time-of-flight mass spectrometry in data-independent acquisition mode. Sample preparation was performed using protein precipitation on a fully automated robotic setup. Thirteen analogues were selected to validate the method. A small matrix ion enhancement effect (110-123%) was observed for all of the compounds; the recovery ranged from 67% to 81% and the process efficiency from 81% to 98%. Limit of detection was within 0.0005-0.001mg/kg and limit of identification ranged from 0.001 to 0.005mg/kg. In the retrospective analysis of 2339 forensic blood samples, the major finding was fentanyl (n=56), followed by alfentanil (n=5) and remifentanil (n=1). Identification of 34 fentanyl analogues was based on the predicted product ions resulting from common fentanyl-specific collision-induced cleavages, particularly on the product ion result of the fragmentation on the C-N bond between the phenylamide moiety and the piperidine ring. The proposed hypothesis was supported by the targeted analysis of 16 fentanyl analogues using this method and available published mass spectral data sources for fentanyl analogues. A targeted screening method for 50 fentanyl analogues was successfully validated and implemented to analyse authentic blood samples, where identifying targeted fentanyl analogues was tentatively achieved without using reference standards.
