Metal-, Photocatalyst-, and Light-Free, Late-Stage C-H Alkylation of Heteroarenes and 1,4-Quinones Using Carboxylic Acids

Contrary to the accepted convention, this work shows that Minisci-type C-H alkylation does not require any metal, photocatalyst, light, or prefunctionalization of the readily available and inexpensive carboxylic acids to proceed well under mild conditions. These mild conditions can be utilized for late-stage alkylations of complex molecules, including pharmaceutical compounds and light-sensitive compounds which degrade under photocatalytic conditions.

Properties of ICI 128,436, a novel aldose reductase inhibitor, and its effects on diabetic complications in the rat

ICI 128,436 (3-(4-bromo-2-fluorobenzyl)-4-oxo-3H-phthalazin-1-ylacetic acid) is a chemically novel, potent inhibitor of aldose reductase. It inhibits partially purified aldose reductase isolated from a number of sources including human tissue (human lens -IC50 2.0 x 10-8 mol/L). Dulcitol accumulation in erythrocytes and sciatic nerves of galactose loaded rats was inhibited by five days of treatment with ICI 128,436 (oral ED50’s 2.21 mg/kg and 8.56 mg/kg, respectively). On oral administration for five days to streptozotocin diabetic rats, ICI 128,436, reduced sorbitol levels in sciatic nerve, lens, retina, and renal cortex. The ED50 for inhibition of nerve sorbitol accumulation was 5 mg/kg. The effect of a single dose of ICI 128,436 in diabetic rats was prolonged, with little increase in nerve sorbitol for 48 hours. No tolerance to the ability of ICI 128,436 to reduce nerve sorbitol was found on treatment for 74 days. ICI 128,436 was effective in rodent models of the neural and lenticular complications of diabetes. At doses as low as 25 mg/kg/d it completely prevented the development of cataracts in diabetic rats. The deterioration in motor nerve conduction velocity found in diabetic rats was ameliorated by treatment with ICI 128,436 (3.125 mg/kg/d). Thus, ICI 128,436 constitutes a chemically novel aldose reductase inhibitor that is now being assessed for therapeutic value in the diabetic patient.

Regioselective Synthesis of Substituted 4-Alkylamino and 4-Arylaminophthalazin-1(2 H)-ones

(Chemical Equation Presented). An efficient regioselective synthesis of substituted 4-alkylamino and 4-arylaminophthalazin-1(1H)-ones 5 is described. This new method features the formation of substituted phthalazin-1(1H)-ones 3 by the reaction of 2-formylbenzoic acids 1 or 3-hydroxyisobenzofuran-1(3H)-ones 2 with hydrazine to generate phthalazin-1(2H)-ones 3. Subsequent regioselective bromination of phthalazin-1(2H)-ones 3 with benzyltrimethylammonium tribromide (BTMA-Br3) followed by mixed copper-copper oxide-catalyzed amination of 4-bromophthalazin-1(2H)-ones 4 with primary amines generates aminophthalazin-1(2H)-ones in good overall yields.

Synthesis and Antitumor Activity of 1-Phenyl-4-substituted Phthalazine Derivatives

In order to find more efficient and economical antitumor drugs, a series of 1-phenyl-4-substituted phthalazine derivatives were synthesized and evaluated for antiproliferative activity in vivo. The structures of the synthesized compounds were confirmed by 1H NMR, 13C NMR and HRMS. The antitumor activity of the target compounds was performed against four cancer cell lines by 3-(4, 5-dimethyl-2-thiazolyl)-2, 5-diphenyl-2-H-tetrazolium bromide (MTT). The results showed that some compounds had a good antitumor activity, especially, N-(4-methoxyphenyl)-2-((4-phenylphthalazin-1-yl) thio) acetamide (5f) and N-(3-chloro-4-fluorophenyl)-2-(4-(4-phenylphthalazin-1-yl) piperazin-1-yl) acetamide (8c), exhibited better antitumor activities with IC50 values of 8.13 and 9.31 mumol?L-1 against the human esophageal cancer cells, which were superior to 5-fuorouracil.

Condensation of anthranilic acids with pyridines to furnish pyridoquinazolones via pyridine dearomatization

The unprecedented carbodiimide-mediated condensation between pyridines and anthranilic acids via pyridine dearomatization at room temperature has been developed to provide a straightforward approach to pyridoquinazolones. The value of this approach has further been demonstrated by its application to one-step, gram-scale syntheses of a series of pyridoquinazolone-based natural products and their analogues from readily available starting materials.

Ionic liquid catalysed multicomponent synthesis, antifungal activity, docking studies and in silico ADMET properties of novel fused Chromeno-Pyrazolo-Phthalazine derivatives

A series of novel chromeno-pyrazolo[1,2-b]phthalazine-6,9,14(7H)-trione derivatives (4a?k) were designed and prepared using a reusable and efficient catalyst ionic liquid [Bmim]BF4 via one-pot multi-component reaction. Their bioactivity was evaluated against Aspergillus niger and Candida albicans in vitro. Compound 4f was found to be the most effective compared to all other synthesised compounds. To validate experimental biological data obtained, molecular docking study was carried out. It was observed that compound 4f showed stronger binding interactions with secreted aspartic proteinase (SAP) of C. albicans (1EAG). Further, primary optimisation of drug-like properties was studied through in silico predictions by using ADMET predictor FAFdrug2 and OSIRIS property explorer.
