Costa, Leticia D.;Guieu, Samuel;Faustino, Maria do Amparo F.;Tome, Augusto C. research published 《 Straightforward synthesis of thiazolo[5,4-c]isoquinolines from dithiooxamide and 2-halobenzaldehydes》, the research content is summarized as follows. The reaction of dithiooxamide using adequately substituted 2-halobenzaldehydes afforded selectively thiazolo[5,4-c]isoquinolines (TzIQ) I [R = 2-FC₆H₄, 2,4-di-ClC₆H₃, 2-O₂NC₆H₄, etc.; R¹ = H, Me, Cl, etc.; R² = H, F, Cl; R³ = H, F, Cl; R⁴ = H, F, Cl] or mixtures of thiazolo[5,4-d]thiazoles (TzTz) II [R⁵ = 2-FC₆H₄, 2-BrC₆H₄, 2,6-di-BrC₆H₃, etc.] and thiazolo[5,4-c]isoquinolines (TzIQ). The use of lanthanum(III) triflate as the catalyst favored the formation of TzIQ. The results obtained using a large number of substituted benzaldehydes showed that the nature, number and position of halogen atoms and other substituents on the aldehyde had a great impact on the reaction outcome. The structures of six TzTz and six TzIQ were unveiled by single-crystal X-ray diffraction.

Bukowska, Agnieszka;Bester, Karol;Pytel, Maciej;Bukowski, Wiktor research published 《 Polymer Beads Decorated with Dendritic Systems as Supports for A³ Coupling Catalysts》, the research content is summarized as follows. The gel type microscopic polymer beads bearing epoxy functionalities were modified using the two-stage procedures in order to decorate their surface with the moieties of the zeroth order PAMAM type dendrimer and different heterocyclic aldehydes (2-pyridinecarboxaldehyde, 2-pyrrolidinecarboxaldehyde, furfural or 2-thiophenecarboxaldehyde). The polymeric supports provided in this manner were then used for the immobilization of copper(II) ions. The resulting materials were characterized using different instrumental techniques (optical microscopy, SEM, FTIR microscopy, DR UV-Vis, ICP-OES, and thermal anal.). They were also used as catalysts in the model A³ coupling reaction of benzaldehyde, morpholine and phenylacetylene. The best catalytic activity was found for the polymeric catalyst bearing 2-pyridinecarboxaldehyde moieties. It turned out to be effective in the A³ coupling reactions included different benzaldehyde, alkyne, and secondary amine derivatives, as well. It could also be recycled several times without a significant decrease in its activity in the model A³ coupling reaction.

Utrophin modulation is a promising therapeutic strategy for Duchenne muscular dystrophy (DMD), which should be applicable to all patient populations. Following on from ezutromid, the first-generation utrophin modulator, we describe the development of a second generation of utrophin modulators, based on the bioisosteric replacement of the sulfone group with a phosphinate ester and substitution of the metabolically labile naphthalene with a haloaryl substituent. The improved physicochem. and absorption, distribution, metabolism, and excretion (ADME) properties, further reflected in the enhanced pharmacokinetic profile of the most advanced compounds, 30 and 27, led to significantly better in vivo exposure compared to ezutromid and alleviation of the dystrophic phenotype in mdx mice. While 30 was found to have dose-limiting hepatotoxicity, 27(I) and its enantiomers exhibited limited off-target effects, resulting in a safe profile and highlighting their potential utility as next-generation utrophin modulators suitable for progression toward a future DMD therapy.

New series of hexahydroquinoline and fused quinoline derivatives were designed and synthesized. The thirty seven new compounds were screened for in vitro antitumor activity against HepG2, HCT-116 and MCF-7 cancer cells. Results indicated that certain compounds, including I, have the strongest potency against the three cancer cells, and they were further screened for in vitro cytotoxicity against A431 and H1975 cancer cells, as well as WI38 and WISH normal cells. Results revealed that I potently inhibited the growth of H1975 cells harboring EGFR^T790M mutation (IC₅₀ = 1.32 ± 0.2μM) over A431 cells overexpressing EGFR^WT (IC₅₀ = 4.96 ± 0.3μM). Moreover, the seven compounds displayed low cytotoxicity against the tested normal cells. The seven potent antitumor compounds were examined for their ability to inhibit the activity of EGFR^WT. The attained data manifested that I has remarkable EGFR^WT inhibitory activity (IC₅₀ = 0.083 ± 0.002μM) compared to erlotinib (IC₅₀ = 0.067 ± 0.002μM). Compound I was further studied for its enzymic inhibitory activity against other eight human kinases, and it displayed outstanding inhibitory activity against EGFR^L858R and EGFR^T790M mutants (IC₅₀ = 0.053 ± 0.002, 0.026 ± 0.001μM, resp.), as well as JAK3 (IC₅₀ = 0.069 ± 0.003μM). Anal. of cell cycle evidenced that I induces cell cycle arrest in G2/M and pre-G1 phases in the tested cancer cells. In addition, cancer cell death induced by I was proved to take place via apoptosis supported by elevated Bax/Bcl-2 ratio in the tested cancer cells. Moreover, docking results confirmed the good binding interactions of I with EGFR^WT, EGFR^L858R, EGFR^T790M and JAK3, which came in agreement with the results of in vitro enzyme assay. Further, I is predicted to have good oral absorption, good drug-likeness properties and low toxicity risks in human.

2,3-DBA is part of a group of Benzaldehyde (B119740) derivatives that exhibit activity against Mycobacterium tuberculosis, the bacteria responsible for causing tuberculosis in humans. 2,3-DBA is also used as a reagent to synthesize (E)-2-(2-arylhydrazinyl)quinoxalines, compounds that have potent anticancer activity., Reference of 6334-18-5
