<span>Phosphodiesterase-IV (PDE- IV) inhibitors which are effective anti-inflammatory agents have forced researchers to find new PDE-IV inhibitors with less adverse effects than conventional anti-inflammatory drugs. Some pyridazinone derivatives reduced inflammation by inhibiting PDE-IV enzyme and acted as anti-inflammatory agents. The new pyridazinone derivatives will be more suitable than the currently developed pyridazinone compounds for future studies and could be developed as more safe anti-inflammatory drugs for humans.</span>

The present work aims to evaluate two native plants including, <em>Hammada scoparia</em> (<em>H. scoparia</em>) and <em>Halocnemum Strobilaceum</em> (<em>H. Strobilaceum)</em>, which grow in Benghazi-Libya for soil phytoremediation purpose. Plants and soil samples were collected and analyzed for Cu, Zn, Fe and Cr concentrations at different sites in the north coastal region of Benghazi. Performance of <em>Hammada scoparia</em> and <em>Halocnemum Strobilaceum </em>was evaluated by calculating biological absorption coefficient (BAC), bioconcentration factor (BCF), and translocation factor (TF). Both plants were found to be a moderate extractor. The tendency of the plants toward phytoextraction process and phytostabiliztion process was studied. Both plants tend to phytoextraction process except <em>Halocnemum Strobilaceum</em> tends strongly to phytostabiliztion process in case of Cu and Fe.

<span lang="EN-CA">Tuberculosis (TB) has been one of the main causes of morbidity, and the emergence of multi-drug resistant (MDR) <em>Mycobacterium tuberculosis</em> strains has become a major concern. The decrease in activity of the major anti-TB drugsincluding, isoniazid, and rifampicin is an important threat that requires an urgent therapy. Anti-TB activity of the fluoroquinolones (FQs) has been under investigation. Many FQs are active in vitro; however, only a few such as ofloxacin, ciprofloxacin, sparfloxacin, levofloxacin, Moxifloxacin, and gatifloxacin have been clinically tested. The FQs can be used in co-therapy with the available anti-TB drugs. Molecular hybridization is a concept of drug design and development based on combination of pharmacophoric moieties of various bioactive compounds to produce a new hybrid compound with improved affinity and efficacy compared with the present drugs.</span>

Design of novel antipsoriatic drugs based on the medicinal compound Tazarotene is the main purpose of the present study. Firstly, the molecular structures of Tazarotene and its derivatives (F, Cl, CH<sub>3</sub>, OCH<sub>3</sub>, COOH, OH, NH<sub>2</sub> and CF<sub>3</sub>) were optimized using density functional theory (DFT) at B3LYP/6-311++G (d, p) computational method. Then, the optimized molecules were docked into the active site of the retinoic acid receptors. The molecular docking analyses revealed that, the Tazarotene derivatives with COOH, CF<sub>3</sub> and OCH<sub>3</sub> substituents can make strongest complexes with RAR-alpha, RAR-beta and RAR-gamma, respectively. Based on the physicochemical properties calculations, it was cleared that the CF<sub>3</sub> derivative of Tazarotene has better properties (receptor-ligand interaction efficiency, lipophilicity and skin permeation) compared with that of the Tazarotene.

<span>Acetaminophen overdose is one of severe global health challenges. In this study, adsorption technique was used to reduce acetaminophen overdose. Carbo tablets derived by wet granulation technique, coded as formulated carbo tablet (FCT) and alginated formulated carbo tablets (FCT-Alg), were characterized using the pharmaceutical drug procedures (hardness, disintegration time, tablet strength, friability) and instrumental techniques including, FTIR, SEM, and DSC analysis. DSC thermogram revealed that, the excipients were compatible with the active pharmaceutical ingredient (API). Batch adsorption experiments were carried out in the simulated gastric fluid (SGF) to monitor the role of some parametric factors (pH, concentration, carbo dosages, and PCM dosages). The tablet displayed favorable hardness and disintegration time (3.40 min). Optimum adsorption was observed at pH 1.2 for FCT in SGF (RE of 92.80%); FCT-Alg in SGF (RE of 99.17%). The results depicted that, the adsorption of the acetaminophen in SGF gave up to 99.65% removal efficiency, and compared with the commercial carbo tablet (CCT) with adsorption efficiency of 96.44%.</span>
