Discovery of anilinopyrimidine-based naphthamide derivatives as potent VEGFR-2 inhibitors

Vascular endothelial growth factor receptor-2 (VEGFR-2) plays an important role in tumor angiogenesis, and inhibition of the VEGFR-2 signaling pathway has emerged as an attractive strategy for the treatment of cancer. Herein, we describe the design, synthesis, and biological evaluation of anilinopyrimidine-based naphthamide derivatives as potent VEGFR-2 inhibitors. Among the new derivatives, compound 3k exhibited high VEGFR-2 inhibitory potency in both enzymatic and VEGF-induced HUVEC cellular proliferation assays (IC50 = 0.5 and 9.8 nM, respectively). Kinase selectivity profiling revealed that 3k was a highly selective VEGFR-2 inhibitor. Moreover, 3k effectively inhibited angiogenesis in HUVEC tube formation assay.

THE DIFFERENTIAL REACTIVITY OF 5- AND 3-METHYL GROUPS IN THE REACTION OF 4-SUBSTITUTED 2,3,5-TRIMETHYLISOXAZOLIUM SALTS WITH AROMATIC ALDEHYDES.

2,3,5-Trimethylisoxazolium salts with electron-withdrawing groups at C-4 react with aromatic aldehydes to give 3- and/or 5-arylidene derivatives resulting from the condensation at CH3-3 and/or CH3-5.The differential reactivity of 3- and 5-methyl groups is markedly influenced by the nature of the substituent at C-4 and varies in the same order as its kinetic acidity which was estimated from studies on deuteriodeprotonation.The influence of inductive, resonance and steric effects due to the 4-substituents on the course of the reaction is shown.

Energetic and topological approach for characterization of supramolecular clusters in organic crystals

In this work, an approach is proposed for understanding the crystal arrangements of organic compounds. The crystals are studied taking into account the stabilization energy and the topological properties like contact surfaces of a molecule (M1) due to the presence of neighboring Mn (cluster). The molecular system models chosen were five heterocycles and one beta-enaminone. The cluster of compounds had a Molecular Coordination Number (MCN) of 14, except for one compound that had an MCN of 16. Our study showed that intermolecular interactions can be divided into four main types: type I, with large energy values and a small contact surface; type II, involving a large value for both the energy and the contact surface; type III, with small and medium energy values, and a medium-sized contact surface; and type IV, with small energy values and a relatively large contact surface. Additionally, from this approach we show that only from the supramolecular cluster is it possible to observe the participation of the topological component during the formation of the crystal. This is demonstrated by the fact that the fragility of the electrostatic interaction between M1 and one Mn in the same plane is compensated by a strong interaction of M1 with a molecule in another plane.

Synthesis, characterization and biological activity of some new heterocyclic compounds derived from 4- aminoacetophenone

Our work aimed for organic synthesis and biological investigation of some new heterocyclic derivatives by three steps: the first step included synthesis of some five-membered and six-membered heterocyclic derivatives (Pyrazole, Isoxazole, Oxazine and Thiazine) from Chalcone. The second step included synthesis of some 1,3-Oxazipene derivatives from Schiff’s bases derived from Azo compound. The third step included the assay of biological activity of all compounds against four types of pathogens bacteria (Staphylococcus aureus, Granutice tella adiacens) gram positive and ( E. coli, Proteus mirabilis) gram negative the results exhibited excellent biological activity for all derivatives compared to antibiotics (Ampicillin and Ciprofloxacin). These compounds were identified and confirmed by FT- IR, 1HNMR, 13CNMR and elemental analysis.

Substitution at Tricoordinate Sulfur(IV). Rearrangement of Sulfinanilides to Anilino Sulfoxides

Seven N-methyl-N-aryl-p-toluenesulfinamides (1, 3-Me2NC6H4; 2, 3-MeOC6H4; 3, 4-MeOC6H4; 4, 3-MeC6H4; 5, Ph; 6, 3-ClC6H4; 7, 3-FC6H4), N-(3-methoxyphenyl)-p-toluenesulfinamide (8), and two N-methyl-N-aryl-methanesulfinamides (9, 3-Me2NC6H4; 10, 3-MeOC6H4) were prepared from the corresponding sulfinyl chloride and the substituted aniline.Sulfinanilides 2 and 7 were treated with alkyllithiums in vain attempts to induce rearrangement to the diaryl sulfoxides via endocyclic nucleophilic attack by carbon 2 of the aniline ring on sulfur.Instead, the alkyllithium cleaved the S-N bond to yield the aniline and alkyl p-tolyl sulfoxide.Upon treatment with gaseous HCl in chloroform, the sulfinanilides rearranged as follows: 1 gave 4-(dimethylamino)-2-(methylamino)-4′-methyldiphenyl sulfoxide (92percent yield), 2 gave 2-methoxy-4-(methylamino)-4′-methyldiphenyl sulfoxide (26percent yield) and 4-methoxy-2-(methylamino)-4′-methyldiphenyl sulfoxide (70percent yield), 4 gave 2-methyl-4-(methylamino)-4′-methyldiphenyl sulfoxide (71percent yield), 9 gave methyl 4-(dimethylamino)-2-(methylamino)phenylsulfoxide (20percent yield), and 10 gave methyl 2-methoxy-4-(methylamino)phenyl sulfoxide (5percent yield).Sulfinanilides 3 and 5-8 did not rearrange.A tentative mechanism for the rearrangement is proposed.
