Isoxazole?a potent pharmacophore

Isoxazole is an azole with an oxygen atom next to the nitrogen. Isoxazole rings are found in some natural products, such as ibotenic acid and also found in a number of drugs, including COX-2 inhibitor valdecoxib. Furoxan, a nitric oxide donor is containing isoxazolyl group and found in many beta-lactamase resistant antibiotics, such as cloxacillin, dicloxacillin and flucloxacillin. The synthetic androgenic steroid danazol also has an isoxazole ring. The substituted isoxazoles are well developed in literature to possess significant biological activities. The disubstituted and trisubstituted isoxazoles have been reported to exhibit broad range of biological activities such as antimicrobial activity, analgesic activity, anti-inflammatory activity, antioxidant activity, anticancer activity, CNS (central nervous system) activity, antitubercular activity and miscellaneous activities like GABA (gamma-amino butyric acid) agonistic activity, inhibitory activity, antihypertensive activity, and glutamate transporter activity. The present review summarizes up to date information of various biological activities of isoxazole analogs.

Sulfur containing acridine derivatives in preclinical studies with cancer cell lines

Background: The possible use of acridines as anticancer agents was first considered in the 1920?s. Since then, a large number of acridine drugs have been tested as antitumour agents, including compounds containing sulphur on the acridine chromophore. In this review, we will discuss recent studies which have investigated the anticancer activity of this class of acridine derivatives. Methods: We present the results both of our own decade-long research and also of existing research literature into the anticancer activity of acridine derivatives containing sulphur. The evidence of specific tumor-cell killing properties displayed by these compounds suggest the potential of using such molecules as anticancer therapeutics. Results: During the last decade, a number of acridine analogs have been developed by modifying the position and the nature of the substituent on the acridine core. In this paper, we published results on the anticancer activity of acridine derivatives containing sulfur (acridine thioureas, acridine thiazolidine/thiazoidinone, and acridine thiosemicarbazones/ thiosemicarbazides). In cancer chemotherapy, the mechanism of the drugs is complex, although the study of the anticancer activity of acridines has yielded exciting results. Conclusion: In this review we have summarized recent literature on the anticancer activity of acridine derivatives containing sulfur. A considerable amount of published data suggests that these compounds exhibit promising anticancer activity against selected cancer cell lines. The obtained results can be helpful in the development of new pharmaceutical agents.

Herein, we report a metal-free synthesis of cyclic amidines, oxazines, and an oxazinone under mild conditions by electrophilic amide activation. This strategy features an unusual Umpolung cyclization mode and enables the smooth union of alpha-aryl amides and diverse alkylazides, effectively rerouting our previously reported alpha-amination transform.

Discovery of 1,3-diphenyl-1H-pyrazole derivatives containing rhodanine-3-alkanoic acid groups as potential PTP1B inhibitors

Two series of 1,3-diphenyl-1H-pyrazole derivatives containing rhodanine-3-alkanoic acid groups were identified as competitive protein tyrosine phosphatase 1B (PTP1B) inhibitors. Among the compounds studied, IIIv was found to have the best in vitro inhibition activity against PTP1B (IC50 = 0.67 ¡À 0.09 muM) and the best selectivity (9-fold) between PTP1B and T-cell protein tyrosine phosphatase (TCPTP). Molecular docking studies demonstrated that compounds IIIm, IIIv and IVg could occupy simultaneously at both the catalytic site and the adjacent pTyr binding site. These results provide novel lead compounds for the design of inhibitors of PTP1B as well as other PTPs.

Chiral ferrocenylthiazolidines, new ligands for palladium complexes

The reaction of ferrocene with methyl or ethyl esters of L-cysteine in the presence of paraformaldehyde is studied. This process yields the optically pure derivatives: methyl or ethyl (R)-3-(ferrocenylmethyl)thiazolidine-4-carboxylates (1a or 1b), together with the corresponding N,N-bisthiazolidine derivatives (2a or 2b). When the reaction was carried out using the ethyl ester of L-cysteine, small amounts (ca. 9%) of the 1,1′-disubstituted ferrocene derivative (3b) were also isolated. The reactivity of compounds 1 versus palladium(II) species is studied, and has allowed us to isolate and characterise: [Pd(eta3-C3H5)Br(1a)] (4a) and [Pd(eta3-C3H5)Br(1b)] (4b), in which the ferrocenyl ligand behaves as a monodentate S-donor group. Compounds 4 evolve in the presence of dimethylsulfoxide to produce: [Pd(eta1-C3H5)Br(1)(dmso)] (5) in which the palladium(II) is bound to the terminal carbon of the C3H5 group. The reactivity of ligands 1 with Na2[PdCl4] is also reported and has allowed us to isolate the dinuclear compounds [Pd2Cl4(mu-1a)2] (6a) and [Pd2Cl4(mu-1b)2] (6b)] in which the thiazolidine behaves as a bridging (N,S) donor group.

Advances in gene editing technology and human pluripotent stem cell differentiation techniques have expanded the capability of HTS to identify potential treatments for human diseases of the central nervous system. Here, we describe techniques to use a human patient-derived neural progenitor cell luciferase reporter line to screen a large small molecule library.
