The complete assignments have been performed on the basis of the experimental data and potential energy distribution (PED) of the vibrational modes. The calculated HOMO and LUMO energies and energy difference (Delta EHOMO-LUMO = 4.876 eV), confirm that charge transfers occur within the molecule. The stability of the molecule arising from hyperconjugative interactions and the charge delocalization has been analyzed using natural bond orbital’s analysis (NBO). The specific heat, Gibb’s free energy, and entropy of molecule have been calculated as a function of temperature by using statistical mechanics coupled with quantum chemical calculation.

In an article, author is Sanchez-Moreno, Manuel, once mentioned the application of 24324-17-2, Quality Control of 9-Fluorenemethanol, Name is 9-Fluorenemethanol, molecular formula is C14H12O, molecular weight is 196.2445, MDL number is MFCD00001139, category is phthalazine. Now introduce a scientific discovery about this category.

Objectives: To evaluate the in vitro leishmanicidal activity of imidazole-based (1-4) and pyrazole-based (5-6) benzo[g] phthalazine derivatives against Leishmania infantum and Leishmania braziliensis. Methods: The in vitro activity of compounds 1-6 was assayed on extracellular promastigote and axenic amastigote forms, and on intracellular amastigote forms of the parasites. Infectivity and cytotoxicity tests were performed on J774.2 macrophage cells using meglumine antimoniate (Glucantime) as the reference drug. The mechanisms of action were analysed by iron superoxide dismutase (Fe-SOD) and copper/zinc superoxide dismutase (CuZn-SOD) inhibition, metabolite excretion and transmission electronic microscopy (TEM). Results: Compounds 1-6 were more active and less toxic than meglumine antimoniate. Data on infection rates and amastigote mean numbers showed that 2, 4 and 6 were more active than 1, 3 and 5 in both L. infantum and L. braziliensis. The inhibitory effect of these compounds on the antioxidant enzyme Fe-SOD of promastigote forms of the parasites was remarkable, whereas inhibition of human CuZn-SOD was negligible. The ultrastructural alterations observed in treated promastigote forms confirmed the greater cell damage caused by the most active compounds 2, 4 and 6. The modifications observed by 1H-NMR in the nature and amounts of catabolites excreted by the parasites after treatment with 1-6 suggested that the catabolic mechanisms could depend on the structure of the side chains linked to the benzo[g] phthalazine moiety. Conclusions: All the compounds assayed were active in vitro against the two Leishmania species and were less toxic against mammalian cells than the reference drug, but the monosubstituted compounds were significantly more effective and less toxic than their disubstituted counterparts.
