N,N-dimethylformamide (DMF) as synthetic precursors contributing especially the methyl, acyl, and amino groups has played a significant role in heterocycle syntheses and functionalization. In this protocol, a wide range of pyrrolo/indolo[1,2-a]quinoxalines and quinazolin-4-ones were obtained in moderate to good yields by using elemental iodine without any metal or peroxides. We considered thatN-methyl andN-acyl of DMF participate and complete the reaction separately through different mechanisms, which displayed potential still to be explored of DMF.

An efficient transformation of 2-aminobenzamides to 1,2,3-benzotriazin-4(3H)-ones in the presence of sodium nitrite (NaNO2) and Iodine (I2) is described. The reaction is proposed to proceed via formation of nitrosyl halide that induces nitrosylation of the amino group of 2-aminobenzamide leading to diazotization followed by intramolecular cyclization.

Alcohols and ethers were identified as sustainable methine sources for synthesizing quinazolinone and benzimidazole derivatives using a combination of TsOH·H2O/O2 and appropriate bis-nucleophiles for the first time. Deuterium labeling studies clearly proved that the C2 hydrogen of the synthesized heterocycles came from the methine source. These unique reaction conditions were successfully applied to the synthesis of echinozolinone (2e′), 2f′ (a common precursor of rutaecarpine and (±) evodiamine), and dimedazole (6d). Notable features of this method include its low toxicity, use of commercial feedstocks as substrates, low cost, broad functional group tolerance and suitability for a wide range of bis-nucleophilic starting materials.

A sulfur-promoted three-component reaction of isatoic anhydride, primary aliphatic or aromatic amines, and acetophenones leading to densely substituted 3-substituted 2-aroylquinazolin-4(3H)-ones is reported. The key step involves a cascade reaction of selective oxidation of the methyl group of the acetophenones, followed by a condensation with anthranilamides. The scope of the reaction is applicable to the synthesis of tryptanthrin and various 3-unsubstituted 2-aroylquinazolin-4(3H)-ones. (Figure presented.).

A novel palladium-catalyzed oxidative three-component coupling of easily accessible N-substituted anthranilamides with isocyanides and arylboronic acids is achieved. This protocol offers an alternative approach toward 2,3-disubstituted quinazolinones with a wide substrate scope and good functional group tolerance.

Thrombin (factor IIa) and factor Xa (FXa) are key enzymes at the junction of the intrinsic and extrinsic coagulation pathways and are the most attractive pharmacological targets for the development of novel anticoagulants. Twenty non-amidino N2-thiophencarbonyl- and N2-tosyl anthranilamides 1-20 and six amidino N2-thiophencarbonyl- and N2-tosylanthranilamides 21-26 were synthesized to evaluate their activated partial thromboplastin time (aPTT) and prothrombin time (PT) using human plasma at a concentration of 30 μg/mL in vitro. As a result, compounds 5, 9, and 21-23 were selected to study the further antithrombotic activity. The anticoagulant properties of 5, 9, and 21-23 significantly exhibited a concentration-dependent prolongation of in vitro PT and aPTT, in vivo bleeding time, and ex vivo clotting time. These compounds concentration-dependently inhibited the activities of thrombin and FXa and inhibited the generation of thrombin and FXa in human endothelial cells. In addition, data showed that 5, 9, and 21-23 significantly inhibited thrombin catalyzed fibrin polymerization and mouse platelet aggregation and inhibited platelet aggregation induced by U46619 in vitro and ex vivo. Among the derivatives evaluated, N-(30-amidinophenyl)-2-((thiophen-200-yl)carbonylamino)benzamide (21) was the most active compound.

We recently reported the synthesis and quantitative structure-activity relationships of a new breast cancer resistance protein (BCRP) inhibitor class. In the study presented herein, we investigated the possibility to better define the scaffold of this compound class by removing or modifying the aromatic ring A with various substituents selected on the basis of their electronic and lipophilic properties. The results show that this aromatic ring is important, but not essential, for activity. Many of the selected substituents led to compounds with low activity, but in some cases activity was retained. Among these, a phenolic hydroxy group proved to impart as much potency to the molecule as a hydroxyethyl side chain, initially considered necessary for activity. This derivative is one of the most active compounds in this class, maintaining an inhibitory activity similar to that of the reference compound; it is also selective for BCRP.

A green synthesis and intriguing solvatochromic behaviour of 2-aminobenzamide derivatives in varying solvents has been investigated. The biomaterial in the form of an aqueous extract of mesocarp of the fruit of the Balanites roxburghii plant as a natural surfactant reaction medium has been employed for phytosynthesis with quantitative yield at 60 °C. The reaction proceeds effortlessly in a short reaction time with easy product formation. The fluorescence property of some synthesized compounds was studied, along with the interesting solvatochromic behaviour of 2-amino-N-benzylbenzamide.
