I2/TBHP-Mediated tandem cyclization and oxidation reaction: Facile access to 2-substituted thiazoles and benzothiazoles

The efficient synthesis of 2-substituted thiazoles and benzothiazoles has been accomplished employing readily available cysteine esters and 2-aminobenzenethiols as N and S sources. The reaction proceeds under an I2/TBHP system and involves a one-pot tandem cyclization and oxidation sequence. A diverse range of aldehydes is amenable for this transition-metal-free protocol, which provides an alternative method to rapidly access thiazole-containing molecules.

Palladium-catalysed direct cross-coupling of secondary alkyllithium reagents

Palladium-catalysed cross-coupling of secondary C(sp3) organometallic reagents has been a long-standing challenge in organic synthesis, due to the problems associated with undesired isomerisation or the formation of reduction products. Based on our recently developed catalytic C-C bond formation with organolithium reagents, herein we present a Pd-catalysed cross-coupling of secondary alkyllithium reagents with aryl and alkenyl bromides. The reaction proceeds at room temperature and on short timescales with high selectivity and yields. This methodology is also applicable to hindered aryl bromides, which are a major challenge in the field of metal catalysed cross-coupling reactions.

Synthesis and structure-activity relationships of novel lincomycin derivatives. Part 1. Newly generated antibacterial activities against Gram-positive bacteria with erm gene by C-7 modification

We synthesized 7(S)-7-deoxy-7-arylthiolincomycin derivatives possessing a heterocyclic ring at the C-7 position via sulfur atom by either Mitsunobu reaction of 2,3,4-tris-O-(trimethylsiliyl)lincomycin or S N 2 reaction of 7-O-methanesulfonyl-2,3,4-tri-O-trimethylsiliyllincomycin. As a result, 7(S)-7-deoxy-7-arylthiolincomycin derivatives 16, 21 and 27 exhibited antibacterial activities against respiratory infection-related Gram-positive bacteria with erm gene, although clindamycin did not have any activities against those pathogens. Furthermore, 7(S)-configuration of lincomycin derivatives was found to be necessary for enhancing antibacterial activities from the comparison results of configurations of 16 (S-configuration) and 30 (R-configuration) at the 7-position.

Synthesis and biological evaluation of thiabendazole derivatives as anti-angiogenesis and vascular disrupting agents

Abstract Thiabendazole, already approved by FDA for oral use as an anti-fungal and anti-helminthic drug since 1967, has recently been repurposed as a vascular disrupting agent. By optimization of the structure of the lead compound, we successfully identified compound TBZ-19 and the new derivative is over 100-fold more potent than the lead compound against the growth of four different cell lines (A549, HCT-116, HepG2 and HUVECs). The most potent two candidates TBZ-07 and TBZ-19, exhibiting moderate inhibitory cell proliferation activity, were also verified as anti-angiogenesis and vascular disrupting agents. Therefore, TBZ-07 and TBZ-19 would be promising candidates with vasculature targeting activity and merit further development.

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.Safety of Thiazole-4-carboxaldehyde, you can also check out more blogs about3364-80-5

Predicting the genotoxicity of thiophene derivatives from molecular structure

We report several binary classification models that directly link the genetic toxicity of a series of 140 thiophene derivatives with information derived from the compounds’ molecular structure. Genetic toxicity was measured using an SOS Chromotest. IMAX (maximal SOS induction factor) values were recorded for each of the 140 compounds both in the presence and in the absence of S9 rat liver homogenate. Compounds were classified as genotoxic if IMAX ?1.5 in either test or nongenotoxic if IMAX < 1.5 for both tests. The molecular structures were represented by numerical descriptors that encoded the topological, geometric, electronic, and polar surface area properties of the thiophene derivatives. The classification models used were linear discriminant analysis (LDA), k-nearest neighbor classification (k-NN), and the probabilistic neural network (PNN). These were used in conjunction with either a genetic algorithm or a generalized simulated annealing to find optimal subsets of descriptors for each classifier. The quality of the resulting models was determined by the number of misclassified compounds, with preference given to models that produced fewer false negative classifications. Model sizes ranged from seven descriptors for LDA to three descriptors for k-NN and PNN. Very good classification results were obtained with all three classifiers. Classification rates for the LDA, k-NN, and PNN models were 80, 85, and 85%, respectively, for the prediction set compounds. Additionally, a consensus model was generated that incorporated all three of the basic model types. This consensus model correctly predicted the genotoxicity of 95% of the prediction set compounds.

Discovery and SAR of 2-aminothiazole inhibitors of cyclin-dependent kinase 5/p25 as a potential treatment for Alzheimer’s disease

High-throughput screening with cyclin-dependent kinase 5 (cdk5)/p25 led to the discovery of N-(5-isopropyl-thiazol-2-yl)isobutyramide (1). This compound is an equipotent inhibitor of cdk5 and cyclin-dependent kinase 2 (cdk2)/cyclin E (IC50 = ca. 320 nM). Parallel and directed synthesis techniques were utilized to explore the SAR of this series. Up to 60-fold improvements in potency at cdk5 and 12-fold selectivity over cdk2 were achieved.

Synthesis, in vitro alpha-glucosidase inhibitory activity and molecular docking studies of novel benzothiazole-triazole derivatives

Benzothiazole-triazole derivatives 6a?6s have been synthesized and characterized by1H-NMR and13C-NMR. All synthetic compounds were screened for their in vitro alpha-glucosidase inhibitory activity by using Baker?s yeast alpha-glucosidase enzyme. The majority of compounds exhibited a varying degree of alpha-glucosidase inhibitory activity with IC50 values between 20.7 and 61.1 muM when compared with standard acarbose (IC50 = 817.38 muM). Among the series, compound 6s (IC50 = 20.7 muM) bearing a chlorine group at the 5-position of the benzothiazole ring and a tert-butyl group at the para position of the phenyl ring, was found to be the most active compound. Preliminary structure-activity relationships were established. Molecular docking studies were performed to predict the binding interaction of the compounds in the binding pocket of the enzyme.

Iron-catalyzed direct C-H arylation of heterocycles and quinones with arylboronic acids

The arylation of C-H bonds to generate heteroaryl-aryl (Het-Ar) and arylated quinone (Quin-Ar) compounds has received great attention to achieve sustainable goals in synthetic chemistry. Despite significant advances, arylation of a broad range of Het-Ar and Quin-Ar derivatives remains a challenging task. Herein, a variety of heterocycles are arylated by using arylboronic acids in the presence of catalytic amounts of inexpensive Fe(NO 3)3. The C-arylated quinone compounds can be prepared by reacting arylboronic acids with either quinone or hydroquinone. The present method is operationally simple, scalable, does not require prefunctionalization of the heterocycle or quinone, and can tolerate a wide variety of functional groups in the coupling partners. These qualities are expected to render this method attractive for academic and industrial use. Direct C-H arylation of a variety of heterocycles and quinones with arylboronic acids has been developed. An inexpensive iron catalyst, Fe(NO3)3, and a co-oxidant, persulfate, were used in air. The protocol is applicable for large-scale synthesis and is expected to find application as a result of its operational simplicity. Copyright
