Poly(ADP-ribose) polymerase (PARP) members PARP1 and PARP14 belong to an 18-member superfamily of post-translational modifying enzymes. A library of 9 novel non-NAD analog amine compounds was designed, synthesized and evaluated for inhibitory activity against PARP1 and PARP14. Both in silico studies and in vitro assays identified compound 2 as a potential PARP1 inhibitor, inhibiting activity by 93 ± 2% (PARP14 inhibition: 0 ± 6%), and 7 as a potential PARP14 inhibitor, inhibiting activity by 91 ± 2% (PARP1 inhibition: 18 ± 4%), at 10-μm concentration. Key in silico interactions with TYR907 in PARP1 and TYR1620 and TYR1646 in PARP14 have been identified. Compound 2 and compound 7 have been identified as potential leads for the development of selective PARP inhibitors.

The new series of 2-phenylpyrazoline derivatives (2a-j) were synthesized and evaluated for their antimicrobial, in silico and in vitro anticancer activity was performed by MTT assay using MDA-MB-231 (human breast adenocarcinoma) cell line. The 2-phenylpyrazoline derivatives (2a-j) were obtained by the cyclization of chalcones with phenylhydrazine hydrochloride. Synthesized compounds were confirmed using FT-IR, 1H NMR and 13C NMR spectral data. Molecular docking studies were carried out using Auto Dock Tool version 1.5.6 and Auto dock version 4.2.5.1 docking program. in silico Docking study, compound 2d showed good binding score and good binding interaction with selected bacterial proteins and breast cancer protein. Based on this result, compound 2d was performed the anticancer activity by MTT assay method. From this result, compound 2d shown the LC50 value is 185.30 ± 1. 469 μg/mL. From the antibacterial activity compound 2i (2,3-dichloro substituted 2-pyrazoline derivative) showed a good zone of inhibition at high concentration (100 mg/mL) as compared to other derivatives (2a-j) and compound 2c (fluoro substituted 2-phenylpyrazoline derivative) showed a good zone of inhibition at low concentration (25 mg/mL) compared to other derivative (2a-j).

Background: Many drugs are delivered intranasally for local or systemic effect, typically in the form of droplets or aerosols. Because of the high cost of in vivo studies, drug developers and researchers often turn to in vitro or in silico testing when first evaluating the behavior and properties of intranasal drug delivery devices and formulations. Recent advances in manufacturing and computer technologies have allowed for increasingly realistic and sophisticated in vitro and in silico reconstructions of the human nasal airways. Objective: To perform a summary of advances in understanding of intranasal drug delivery based on recent in vitro and in silico studies. Conclusion: The turbinates are a common target for local drug delivery applications, and while nasal sprays are able to reach this region, there is currently no broad consensus across the in vitro and in silico literature concerning optimal parameters for device design, formulation properties and patient technique which would maximize turbinate deposition. Nebulizers are able to more easily target the turbinates, but come with the disadvantage of significant lung deposition. Targeting of the olfactory region of the nasal cavity has been explored for potential treatment of central nervous system conditions. Conventional intranasal devices, such as nasal sprays and nebulizers, deliver very little dose to the olfactory region. Recent progress in our understanding of intranasal delivery will be useful in the development of the next generation of intranasal drug delivery devices.

Aim and Objective: Lipoxygenase (LOX) enzymes play an important role in the pathophysiology of several inflammatory and allergic diseases including bronchial asthma, allergic rhinitis, atopic dermatitis, allergic conjunctivitis, rheumatoid arthritis and chronic obstructive pulmonary disease. Inhibitors of the LOX are believed to be an ideal approach in the treatment of diseases caused by its over-expression. In this regard, several synthetic and natural agents are under investigation worldwide. Alkaloids are the most thoroughly investigated class of natural compounds with outstanding past in clinically useful drugs. In this article, we have discussed various alkaloids of plant origin that have already shown lipoxygenase inhibition in-vitro with possible correlation in in silico studies. Materials and Methods: Molecular docking studies were performed using MOE (Molecular Operating Environment) software. Among the ten reported LOX alkaloids inhibitors, derived from plant, compounds 4, 2, 3 and 1 showed excellent docking scores and receptor sensitivity. Result and Conclusion: These compounds already exhibited in vitro lipoxygenase inhibition and the MOE results strongly correlated with the experimental results. On the basis of these in vitro assays and computer aided results, we suggest that these compounds need further detail in vivo studies and clinical trial for the discovery of new more effective and safe lipoxygenase inhibitors. In conclusion, these results might be useful in the design of new and potential lipoxygenase (LOX) inhibitors.
