A series of stable N-acyl benzoazetinones have been synthesized in moderate to good yields (58–85%) from easily available substrates such as 2-(N-acyl) amino benzoic acids through intramolecular amidation under mild conditions. These geometry-optimized benzoazetinones were docked in the model target of P450, class CYP53A15, a benzoate 4-monooxygenase abundantly found in the genome of ascomycetes and Basidiomycetes classes of pathogenic fungi. Low per residue root-mean-square deviation (RMSD) of modeled structure of the enzyme indicated similar topology as template (4D6Z.pdb). Observed score judges site-specific docking, and the interaction of quantum mechanically optimized benzoazetinone derivatives with the target enzyme. These results suggest that 3i is the best antifungal agent. The specific hydrophobic substituent in the benzoazetinones contributed to the stability of ligand–target complex. Overall, the study provided insight into the specificity of the site-specific interactions, thereby, facilitating the possibility of development of broad-spectrum antifungal agents against opportunistic and infectious fungi.

A method of treatment of a disease of the human or animal body mediated by PARP comprising administering to such a subject a therapeutically effective amount of a compound of formula: or an isomer, salt, solvate, chemically protected form, and prodrug thereof, wherein: A and B together represent an optionally substituted, fused aromatic ring; RC is represented by —L—RL, where L is of formula: —(CH2)n1—Qn2—(CH2)n3— wherein n1, n2 and n3 are each selected from 0, 1, 2 and 3, the sum of n1, n2 and n3 is 1, 2 or 3 and Q is selected from O, S, NH, C(═O) or —CR1R2—, where R1 and R2 are independently selected from hydrogen, halogen or optionally substituted C1-7 alkyl, or may together with the carbon atom to which they are attached form a C3-7 cyclic alkyl group, which may be saturated (a C3-7 cycloalkyl group) or unsaturated (a C3-7 cycloalkenyl group), or one of R1 and R2 may be attached to an atom in RL to form an unsaturated C3-7 cycloalkenyl group which comprises the carbon atoms to which R1 and R2 are attached in Q, —(CH2)n3— (if present) and part of RL; and RL is optionally substituted C5-20 aryl; and RN is selected from hydrogen, optionally substituted C1-7 alkyl, C3-20 heterocyclyl, and C5-20 aryl, hydroxy, ether, nitro, amino, amido, thiol, thioether, sulfoxide and sulfone.
