Introduction: Acute myeloid leukemia (AML) represents a disease with a very poor outcome and remains an area of significant unmet need necessitating novel therapeutic strategies. Among novel therapeutic agents, vosaroxin is a first-in-class anticancer quinolone derivative that targets topoisomerase II and induces site-selective double-strand breaks in DNA, leading to tumor cell apoptosis. Areas covered: Herein, the authors provide a comprehensive review of the preclinical development of vosaroxin. This includes coverage of vosaroxin’s mechanism of action in addition to its pharmacology and of the main studies reported over the past few years with vosaroxin when used to treat adult AML. Expert opinion: Given that vosaroxin is associated with fewer potential side effects, it may be of benefit to elderly patients with relapsed/refractory AML and to those with additional comorbidities who have previously received an anthracycline and cytarabine combination. Furthermore, vosaroxin also was seen to be active in multidrug-resistant preclinical models. However, further studies have to be performed to better evaluate its place in the armamentarium against AML.

Reaction of BIN center dot HBr with Ag2O, followed by transmetalation with PdCl2(COD)(2) provides a cis complex PdCl2(kC(2)-BIN)(2) (1). Treatment of BIN center dot HBr with W(CO)(4)(pipeddine)(2) in acetonitrile affords a chelate complex W(CO)(4)(k(2)C(2),N-1′-BIN) (2). Reaction of {RhCl(COD)}(2) with KOBu and subsequent treatment with BIN center dot HBr in 1:2 and 1:1 ratio results in the mono and dinuclear complexes [Rh(COD)Br(KC2-BIN)] (3) and [{Rh(COD)Br)(2)(KN8′:C-K(2)-BIN)] (4), respectively. In complex 3, the Rh(COD)Br unit is coordinated to the carbene center, whereas an additional Rh(COD)Br unit is attached to naphthyridine nitrogen in complex 4 in an anti arrangement. Under identical reaction condition, a novel Ir(III) complex [Ir((KC2)-C-2,N-1′-BIN)((KC3)-C-2′,C-2-BIN)(H2O)Br]Br (5) has been synthesized. Complex 5 is proved to be catalytically active in hydrogen transfer reaction from PrOH. All complexes have been characterized by spectroscopic methods and X-ray crystallography.

The microwave-enhanced synthesis of 2-chloro-3-formylbenzo[1,8]naphthyridines 3a-c has been achieved rapidly in good yield via the Vilsmeier-Haack cyclisation of N-(4-methylquinolin-2yl) acetamide 2a-d. The precursors N-(4-methylquinolin-2-yl) acetamide derivatives were effectively prepared in a single step from 2-aminoquinoline and acetic anhydride in presence of Amberlite-120A cation exchange catalyst under microwave irradiation. Condensation of 3a-d, with thioglycolic acid under microwave irradiation using anhydrous potassium carbonate as catalyst afforded thieno[2,3-b]benzo[1,8]naphthyridine-2-carboxylic acids (TBNCS) 4a-g. Elemental analysis, IR, H-1 NMR, and mass spectral studies were used to characterize these compounds. The interaction of thieno[2,3-b] benzo[1,8]naphthyridine-2-carboxylic acid (TBNC)(4a) with CT-DNA was studied by UV-Vis, viscosity as well as thermal denaturation methods. On binding to DNA, the absorption spectrum underwent bathochromic and hypochromic shifts. Binding parameters, determined from spectrophotometeric measurements indicated a binding constant of 1.8 X 10(6) M-1. The thieno[2,3-b]benzo[1,8] naphthyridine-2-carboxylic acid (4a) increases the viscosity of sonicated rod- like DNA fragments. The binding of TBNC to DNA increased the melting temperature by about 4 degrees C. DNA interaction studies suggest that (4a) binds to calf thymus DNA (CT-DNA).
