Hepatotoxicity is a term used to describe serious health complications of liver disease caused by a variety of factors. Nuclear factor erythroid-2 linked factor (Nrf2) as a potential mediator of hepatotoxicity via inflammatory and induction of oxidative stress, oxidation produces more toxic compounds caused more pathogenic cases; therefore, to maintain sufficient homeostasis, involve antioxidant materials and detoxification factors. Controlling cytokine activity in normal cells is a useful way to regulate the signaling pathway of Nrf2. Recent studies found a relation between each Nrf2 and NF-κB activation and drug-induced liver injury. This review presents a detailed and conformation update of Nrf2 roles in hepatotoxicity which considers that drug-induced liver injury is the main problem to draw attention in medical clinics and to develop new drugs with less harmful to the liver. In addition to that. Kept each of normal oxidation and cytokines levels is crucial responses for cells alteration and remaining to survive.

Infections caused by bacteria have a significant impact on public health. Chemical synthesis of new derivatives of cephalexin inked to amino acid (tryptophan or histidine) through an amide bond at the acyl side chain is achieved. This is a new approach of incorporating, tryptophan and histidine into the the primary amino group of cephalexin, in order to provide a bulky group very close to the β-lactam ring. This chemical addition act as isosteric group to the alkoximino that protect beta lactam ring from bacterial beta lactamase enzyme. The new derivatives may show resistance to β-lactamases, improve activity and pharmacokinetic properties and may give new life for old drugs that are susceptible to hydrolysis by most β-lactamases. The chemical structures of these derivatives were confirmed by: FTIR, 1H-NMR spectroscopy, elemental micro analysis and some physical properties. Molecular docking on serine beta lactamase and prediction of ADME parameters were recorded using GOLD suite and Swiss ADME software respectively. Docking scores of the new derivatives of Cephalexin on β-lactamases were higher than those of Cephalexin, which may indicate better activity

Nrf2 is active protein presents in the cytoplasm in the cells of the body. In the presence of an activators, Nrf2 can enter the nucleus which bind to Antioxidant Responses Elements (ARE) or otherwise named human ARE (hARE) which control the whole antioxidants activity in human cell. Many factors may contribute to defective or overwhelmed cellular antioxidants activities for instances aging and cellular damages. These cellular damages can be produced by free radicals or oxidative stress. In the mechanism, if Nrf2 activated in the nucleus, can caused the production of collaborative antioxidants enzymes especially: catalase, glutathione (GLT) and superoxide dismutase (SOD) as a responsible for detoxification of free radical inside the cells.

Among many therapeutic treatments for cancer, nano-carriers are the focus of our review to illustrate the update usage of this drug delivery approach, the most likely side effects and the reality of their potential application with minimum adverse effects. Here, we demonstrate the types of these nano-carriers based on their nature with detailed recent studies about their use. The variation in the skeleton of these nanoparticles enable the selection of the suitable type with higher specifications than others. However, the poor in vivo testing is the main stumbling block for completion of their manufacturing. This review will help the researchers to find the road map for further investigation to finally aid the pharmaceutical companies in manufacturing these nano-carriers in appropriate dosage forms to save the life of millions of people in the world.

In this work we investigate span 40, span 60 and SA as a gelators and olive oil (OO) as apolar liquid phase to discover the ability of organogel formed to be floating in acidic media and gain a unique gastroretentive dosage form. In addition, take advantage of the chemical and physical properties of cinnarizine (CN) as a model drug suitable for gastroretentive systems. The floating parameters were studied where the floating lag time and floating duration for organogel in both solid and liquid states. Organogels charecterization were accomplished through the folowing investigatational techniques and analytical methods: table top rheology, optical microscope, Fourier-transform infrared spectroscopy (FTIR) and in- vitro release study. The results showed that all organogels immediately floated and they were floating in both states. Moreover, table top rheology showed that the transition temperature was reversible and higher than 37 ºC except for 7% w/w and 10% w/w SA in OO organogels where, optical images of organogel showed fibrillar network. The FTIR showed peaks associated to carbonyl groups indicated to form gelator-gelator interactions. Moreover, in vitro release study of organogel system showed continuous release CN for 9-12 hours.
