The Simvastatin loaded microemulsion based gel was formulated and in-vitro evaluation was done for the treatment of diabetic wound healing. Simvastatin is BCS class II drug which promotes wound healing by increasing the production of vascular endothelial growth factor (VEGF). Microemulsions (MEs) are oil and water colloidal system stabilized by the mixture of surfactant and co-surfactant offering enhance skin permeability for both hydrophobic and hydrophilic drugs. At first, microemulsion (ME) was prepared by water titration method and the existence of ME region was determined using pseudo-ternary phase diagram. Formulations were prepared using oil (oleic acid), Tween 80 and PEG 400 as surfactant and co-surfactant. Optimization of formulation was done using 32 factorial designs. Carbopol 940 was used as gelling agent for preparing microemulsion gel. The formulations were evaluated for physical appearance globule size, polydispersity index, zeta potential, percent transmittance, thermodynamic stability, dilution test, drug content, and in vitro drug release. The optimized formulation of ME showed average globule size of 151 nm and the optimized ME gel had a homogeneous texture, showed good spreadability and in vitro drug release. The present study indicates the simvastatin loaded microemulsion gel could act as promising vehicle for topical drug delivery of drug for diabetic wound healing.

Background: The aim of this study is to develop a liquid self-nano emulsifying drug delivery system for alverine (liquid-SNEDDS).Excipients in the alverine SNEDDS include Ethyl oleate as the oil phase, Tween 80 as a surfactant, and PEG600, Propylene glycol as a cosurfactant.The prepared eleven formulations of alverine SNEDDS were performed for emulsification time, percentage transmittance, particle size, drug release, in vitro dissolution and stability studies.The optimised alverine liquid SNEDDS formulation (D1) was studied for drug-excipient compatibility using infrared spectroscopy, as well as particle size, zeta potential, transmission electron microscopy, and stability. Alverine SNEDDS have a spherical shape with uniform particle distribution, according to their morphology. D1's optimised formulation's drug release percentage (96.6). The stability data revealed no discernible changes in drug content, emulsifying properties, drug release, or appearance. As a result, a potential SNEDDS formulation of alverine with improved solubility, dissolution rate, and bioavailability was developed.

Enzymes play very important role in living organism as biocatalyst. They play vital role like secretion, metabolism, digestion, DNA functions, reproduction, conversation of molecules and many other functions of body. By inhibiting specific enzymes, we can cure numerous pathological conditions in humans like inhibiting HMG CoA reductase, we can decrease cholesterol synthesis which is very useful in atherosclerosis and also use for heart diseases. ACE inhibitors can reduce concentration of Angiotensin II and use to reduce blood pressure. Many of them use as pesticides and herbicides in agriculture field. The history says enzyme inhibitors are use as arrow poison and use to kill animals by developing paralysis in them. Using a digital technology scientist identified number of enzymes and their functions as well as their 3D structure. We can easily design their inhibitors and use as medicine to treat pathological conditions. So, enzyme inhibitors became first choice for medicinal chemist and scientist as a target and play extremely important role in future as medicinal compounds and became a safe option compared to other available options.
酶作为生物催化剂在生物体中起着非常重要的作用。它们在人体的分泌、代谢、消化、DNA功能、繁殖、分子对话等许多功能中起着至关重要的作用。通过抑制特定的酶,我们可以治愈人类的许多病理状况,比如抑制HMG辅酶a还原酶,我们可以减少胆固醇的合成,这对动脉粥样硬化非常有用,对心脏病也很有用。ACE抑制剂可以降低血管紧张素II的浓度并用于降低血压。其中许多用作农业领域的杀虫剂和除草剂。历史上说,酶抑制剂被用作箭毒,用来杀死动物,使它们瘫痪。科学家利用数字技术确定了一些酶及其功能以及它们的3D结构。我们可以很容易地设计出它们的抑制剂,并将其用作药物来治疗病理状况。因此,酶抑制剂成为药物化学家和科学家的首选靶标,在未来作为药物化合物发挥着极其重要的作用,与其他可用的选择相比,酶抑制剂成为一种安全的选择。

Emergence of multi-drug resistant isolates of P. mirabilis and development of new resistant microbial phenotypes are growing and the outlook for the use of antimicrobial drugs in the future is still uncertain. Therefore, there is an increased demand for developing alternative strategies to conventional antibiotic therapy and to continue studies to develop new drugs, either synthetic or natural. In this study, 25 isolates of P. mirabilis were isolated from different clinical samples collected from different departments of Tanta University hospitals. All isolates were resistant to amoxicillin, azithromycin and tetracycline. A high incidence of resistance was also recorded for cefprozil (96%) and cefotaxime (80%). P. mirabilis isolates were moderately resistant to imipenem (64%), lomefloxacin (64%), ampicillin (60%), cefepime (60%) and ciprofloxacin (52%). However, the lowest incidence of resistance was recorded for amikacin (8%). All isolates showed MAR indices >0.2 and exhibited MDR profile. The antimicrobial activity of tea tree oil was evaluated using agar dilution method recording MIC50 value of 12.8 mg/ml. The effect of tea tree oil on the strong biofilm producer isolates with relatively wide swarming zone diameters was evaluated. Results obtained showed that tea tree oil (1/4 and 1/2 MIC) presented significant and dose-dependent inhibition in the biofilm production by the tested isolates of P. mirabilis by ≥50%. In addition, tea tree oil inhibited the swarming motility of P. mirabilis isolates in a dose-dependent manner. Therefore, tea tree oil could act as a potential source of alternative antimicrobials or as antipathogenic compound against MDR P.mirabilis.
多重耐药菌株的出现和新的耐药微生物表型的发展正在增加,未来抗菌药物的使用前景仍然不确定。因此,开发常规抗生素治疗的替代策略以及继续研究开发合成或天然新药的需求日益增加。本研究从坦塔大学附属医院不同科室的不同临床样本中分离出25株奇异假单胞菌。所有分离株均对阿莫西林、阿奇霉素和四环素耐药。头孢丙烯(96%)和头孢噻肟(80%)的耐药率也很高。对亚胺培南(64%)、洛美沙星(64%)、氨苄西林(60%)、头孢吡肟(60%)和环丙沙星(52%)均有中等耐药。然而,阿米卡星的耐药发生率最低(8%)。所有分离株的MAR指数均为>0.2,具有MDR特征。用琼脂稀释法测定茶树油的抑菌活性,记录MIC50值为12.8 mg/ml。研究了茶树油对具有较宽蜂群区直径的强生膜菌株的影响。结果表明,茶树油(1/4 MIC和1/2 MIC)对菌株产生生物膜的抑制作用显著且呈剂量依赖性,抑制率≥50%。此外,茶树油抑制奇异假单胞菌的群体运动呈剂量依赖性。因此,茶树油可以作为替代抗菌剂的潜在来源或作为抗耐多药mirabilis的抗致病性化合物。
