New tetradentate Schiff base and its Co(II), Ni(II), Cu(II), Zn(II), Cd(II) and Hg(II) complexes formed by the condensation of 5-fluoro-3-hydrazonoindolin-2-one with isophthalaldehyde. The coloured complexes were prepared of [MLX2], Where L = Schiff base hydrazone, M = Co(II), Ni(II), Cu(II), Zn(II), Cd(II) and Hg(II), X = Cl-. Physico-chemical characterization has been carried out to determine the structure of the complexes. All the synthesized compounds, were studied for their in vitro antibacterial, and antifungal activities, against two Gram-negative (Shigella flexneri and Enterococcus aerogens) and one Gram-positive (Micrococcus luteus,) bacterial strains and against three fungal strains (Candida krusiae Candida parasilopsis and Malassesia pachydermatis) by using cup-plate method. The DNA cleavage capacity of all the complexes was analysed by agarose gel electrophoresis...

Docking is a method which predicts the preferred orientation of one molecule to a second when bound to each other to form a stable complex and is frequently used to predict the binding orientation of small molecule drug candidates to their protein targets and plays an important role in the rational design of drugs. The present study has been focused on the Docking studies of 1,3-disubstituted ureas derivatives as anti-tubercular agents that can explore the binding affinity of ligands to that of the epoxide hydrolase with the help of Schrodinger molecular modelling software. The G-score of the ligand 6s was found to be -8.03 as comparable with the G-score of co-crystallized ligand i.e. -3.77. The carbonyl oxygen of urea moeity of the ligand 6s showed a H-bond interaction with the phenolic oxygen of TYR381 and TYR465 amino acid of the protein residue with distances 2.24Å and 1.67Å respectively and the carbonyl oxygen of urea moeity of the co-crystallized ligand also showed a H-bond interaction with the phenolic oxygen of...

Studies reported from Ethiopia depict poor health outcomes and management of diabetes cases and low patients’ adherence to recommended regimens including medications. Among factors determining adherence to medications that are amenable to interventions are patient perceptions to their recommended medications. This study thus aimed to assess adherence to anti-diabetic medications and determinant factors including medication related beliefs among type 2 diabetic patients attending their treatment in primary healthcare centers of Addis Ababa, Ethiopia using standardized measures. Methodology: A facility-based cross-sectional study design was followed to assess study participants recruited from among type 2 diabetic patients attending their treatment in three health centers in Kirkos Sub City, Addis Ababa from April to June, 2013. For the assessment interviewer administered structured questionnaires based on standardized measures such as the 8-item Morisk’s Medication Adherence Scale (MMAS) and the specific Belief about Medications Questionnaire (BMQ) were used. Result: A total of 155 study participants, all of whom were on oral hypoglycemic agents were involved in the study among whom 53.5% were male and...

Aim: The present study evaluated the anti-diabetic, anti-hyperlipidimeic, antioxidant activities and renal protective effect of aqueous extract from Ganoderma. lucidum fruiting bodies in streptozotocin induced diabetic rats. Material and Results: Qualitative and quantitative phytochemical analysis for G. Lucidum aqueous extract showed the Presence of high concentration of tannins content. Thin layer chromatography (TLC) revealed the presence one tannin spot which high performance liquid chromatography (HPLC) analysis confirmed that the tannin compound is tannic acid. Extracted tannic acid showed highly antioxidant activity in vitro. Two doses of the extract were administered intraperitoneally. Tannic acid significantly decrease blood glucose levels and significant increase in serum insulin in addition, it improved serum lipid profile in diabetic rats compared to untreated diabetic group. Results: Showed that tannic acid also had potent antioxidant activity in vivo, as it significantly decreased MDA while GSH and GPx in erythrocytic and renal tissues were significantly increased. Histopathological examination of kidney tissue tannic acid treated rats showed mild glomerular atrophy and minimal tubular affection with noticeably dilated blood...

The preliminary phytochemical analysis of the aqueous ethanolic extract of the bark of Thespesia populnea (L.) revealed the presence of alkaloids, unsaturated sterols, triterpenes, flavonoids and the absence of anthraquinones. The froth test indicated the presence of saponins. Most importantly this study revealed the presence of proanthocyanidins which has not been reported before. In the present study, ethyl acetate and aqueous soluble proanthocyanidin fractions (EASPA and AQSPA respectively) were extracted and purified by chromatography on Sephadex LH-20. Prussian blue test and acid catalyzed cleavage test revealed that proanthocyanidins have been successfully separated from non-proanthocyanidin phenolics. The yields of purified EASPA and AQSPA fractions were 0.081% and 0.72% (by weight) of the fresh bark. Acid catalyzed cleavage followed by TLC studies of both EASPA and AQSPA fractions showed the presence of two anthocyanidins, cyanidin and delphinidin, suggesting that they are composed of (epi)catechin and (epi)gallocatechin units with (epi)catechin being more abundant compared to the other. This was further confirmed by 13C NMR spectroscopic studies. In addition, 13C NMR spectroscopic studies...
