II. Synthesis and biological evaluation of some bioisosteres and congeners of the antitumor agent, 2-{4-[(7-chloro-2-quinoxalinyl)oxylphenoxy}propionic acid (XK469)

XK469 (1) is among the most highly and broadly active antitumor agents to have been evaluated in our laboratories. Subsequent developmental studies led to the entry of (R)-(+) 1 (NSC 698215) into phase 1 clinical trials (NIH UO1-CA62487). The antitumor mechanism of action of 1 remains to be elucidated, which has prompted a sustained effort to elaborate a pharmacophoric pattern of 1. The present study focused on a strategy of synthesis and biological evaluation of topologically based, bioisosteric replacements of the quinoxaline moiety in the lead compound (1) by quinazoline (4a-d), 1,2,4-benzotriazine (12a-18b), and quinoline (21a-g) ring systems. The synthetic approach to each of the bioisosteres of I utilized the methodology developed in previous work (see Hazeldine, S. T.; Polin, L.; Kushner, J.; Paluch, J.; White, K.; Edelstein, M.; Palomino, E.; Corbett, T. H.; Horwitz, J. P. Design, Synthesis, and Biological Evaluation of Analogues of the Antitumor Agent 2-{4-[(7-Chloro-quinoxalinyl)oxy]phenoxy}propionic acid (XK469). J. Med. Chem. 2001, 44, 1758-1776.), which is extended to the procurement of the benzoxazole (23a,b), benzthiazole (23c,d), pyridine (25a,b), and pyrazine (27) congeners of 1. Only quinoline analogues, bearing a 7-halo (21a,b,d,e) or a 7-methoxy substituent (21g), showed antitumor activities (Br > Cl > CH3O > F ? 1), at levels comparable to or greater than the range of activities manifested by 1 and corresponding analogues. At high individual dosages, the (S)-(-) enantiomers of I and 21b,d all produce a reversible slowing of nerve-conduction velocity in the mice, the onset of which is characterized by a distinctive dysfunction of the hind legs, causing uncoordinated movements. The condition resolves within 5-10 min. However, at higher dosages, which approach a lethal level, the behavior extended to the front legs, lasting from 20 min to 1 h. By contrast, the (R)-(+) forms of these same agents did not induce the phenomenon of slowing of nerve-conduction velocity.

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 2941-48-2 is helpful to your research., Reference of 2941-48-2

Stimuli-responsive nanotheranostics based on lanthanide-doped upconversion nanoparticles for cancer imaging and therapy: current advances and future challenges

Theranostic nanoplatform integrated with concurrent diagnostic and therapeutic capabilities has attracted increasing attentions recently in the field of nanomedicine since it offers great opportunities in the fight against various major diseases, such as cancer. In recent years, lanthanide-doped upconvertion nanoparticles (UCNPs), have been explored for potential applications in cancer diagnostics and treatment owing to their unique merits such as enhancing penetration depths and minimizing background auto?uorescence, photo-bleaching as well as photodamage to biological specimens, and reducing adverse side effects of NIR triggered treatments. Of particular interest is to construct stimuli-responsive nanotheranostic platforms based on UCNPs that imaging and anticancer activities in response to various internal/external stimuli. In this review article, we would like to focus on the recent progress of UCNPs in their applications of stimuli-responsive theranostics that trigger the diagnostic and therapeutic functions in response to various stimuli, including near infrared (NIR) light, pH, glutathione (GSH), reactive oxygen species (ROS), enzyme, and temperature. Furthermore, the future directions and challenges in the development of UCNPs for stimuli-responsive theranostics are discussed.

Syntheses, characterizations and crystal structures of new organotin complexes with 2-mercapto-6-nitrobenzothiazole

A series of organotin(IV) complexes with 2-mercapto-6-nitrobenzothiazole (HMNBT) of the type, [RnSn(MNBT)4-n] (n = 2, R = Me, 4; n = 3, R = Me, 5; n-Bu, 6; Ph, 7; PhCH2, 8) were synthesized. All the complexes 4-8 have been characterized by elemental, IR and 1H NMR analyses. Among them, complexes 4, 7 and 8 were also characterized by X-ray crystallography diffraction analyses, which revealed that the structures of both complexes 7 and 8 are penta-coordinated with R3Sn coordinated to the thiol S and heterocyclic N atoms, and the structural distortion for each is a displacement from tetragonal towards trigonal bipyramidal geometry. For complex 4, the geometry of the center tin atom is a distorted trapezoidal bipyramid. Besides, intermolecular S?S and Sn?S non-bonded interactions were recognized in crystal structures of complexes 4 and 7, respectively. The IR and 1H NMR spectral data indicate such an inclination that those structures of trialkyltin derivatives are apt to be penta-coordinated and those dialkyltin derivatives are likely in six-coordination.

Design, synthesis and SAR exploration of tri-substituted 1,2,4-triazoles as inhibitors of the annexin A2-S100A10 protein interaction

Recent target validation studies have shown that inhibition of the protein interaction between annexin A2 and the S100A10 protein may have potential therapeutic benefits in cancer. Virtual screening identified certain 3,4,5-trisubstituted 4H-1,2,4-triazoles as moderately potent inhibitors of this interaction. A series of analogues were synthesized based on the 1,2,4-triazole scaffold and were evaluated for inhibition of the annexin A2-S100A10 protein interaction in competitive binding assays. 2-[(5-{[(4,6-Dimethylpyrimidin-2-yl)sulfanyl]methyl}-4-(furan-2-ylmethyl)-4H-1,2,4-triazol-3-yl)sulfanyl]-N-[4-(propan-2-yl)phenyl]acetamide (36) showed improved potency and was shown to disrupt the native complex between annexin A2 and S100A10.

Nickel-Catalyzed Reductive Cross-Coupling of (Hetero)Aryl Iodides with Fluorinated Secondary Alkyl Bromides

A mild and efficient nickel-catalyzed reductive cross-coupling between fluorinated secondary alkyl bromides and (hetero)aryl iodides is described. The use of FeBr2 as an additive successfully overcomes the hydrodebromination and beta-fluorine elimination of fluorinated substrates and allows the efficient synthesis of a wide range of trifluoromethyl and difluoroalkyl containing aliphatic compounds with a fluoroalkyl substituted tertiary carbon center. The notable features of this protocol are the synthetic and operational simplicity without preparation of moisture sensitive organometallic reagents and excellent functional group compatibility, even toward active proton containing substrates.
