Author contributions Conflicts of interest Introduction Current the 5-year survival rates for lung and pancreatic cancers are 18% and 8%, respectively. These low survival rates are partially because of the late diagnosis of one-half of cases, in which 5-year survival decrease to 4% and 3%,

2020-11-16
The enzyme cyclooxygenase (COX) or prostaglandin endoperoxide H synthase (PGHS) is the key enzyme in the conversion of arachidonic Chlorhexidine digluconate (AA) into prostaglandins (PGs) [1]. In 1991, researchers found that there were two isoforms of this enzyme called COX-1 and COX-2 with indepen

The first part of the study evaluated the accuracy of recomLine IgG and IgG Avidity to date CMV infection: In our study, 83.1% of samples tested matched onset dates compared to 71.9% with VIDAS avidity. Moreover, the number of inconclusive results (intermediate avidity for VIDAS, positive IgG withou

Similarly to other investigations, the present study found that ZEA in high concentrations decreases viability of both normal (Liu et al., 2018, Zheng et al., 2018a, Zheng et al., 2018b) and cancer ONX-0914 (Khosrokhavar et al., 2009, Kowalska et al., 2017). The toxic effect of ZEA observed by Liu

For immobilization of enzymes, natural polymers depict several outstanding features as support. These materials are inert, non-toxic, biodegradable and biocompatible. As well as, they can be treated with different functional groups easily by chemical reactions that occur under gentle conditions in a

Introduction Enzymes have higher selectivity, specificity and efficiency than chemical catalysts. Due to their properties and their green chemistry, biocatalysts are widely used in food, textile and pharmaceutical industry [1], [2]. A high efficient biocatalyst for industrial applications must be s

The isomeric 5-phenyloxazole not only exhibited increased potency against NEP, but also a decreased ACE inhibition thus providing encouraging selectivity. Changing the P1 group from an -propyl to a more polar methoxyethyl at the left hand CNQX (as seen in compound pairs – and –) decreased ACE inhibi

The monomeric/oligomeric states of DDR2-V5-His and DDR2-Fc were confirmed by Western blotting under reducing and non-reducing conditions. As shown in Fig. 1b, DDR2-V5-His exhibited a relative molecular mass of ~60 kDa under both reducing and non-reducing conditions, consistent with this protein bein

Our research has demonstrated that the absolute bioavailability of oxymatrine, having a similar structure with OSC, was only 6.79±2.52%. About 50% of OSC was converted to its active metabolite SC in vivo; hence, the absolute bioavailability of OSC was speculated to be poor as well [24]. Understandin

In conclusion, we have shown that the cellular effects produced by SFN in NSCLC A-71623 receptor are largely mediated by SFN-induced production of ROS. Cells with higher levels of EGFR were more resistant to SFN treatment and showed resistance to SFN-induced apoptosis, suggesting that high EGFR lev

Oxidation of N hydroxyguanidine by DbH
2020-11-13
Oxidation of N-hydroxyguanidine 1 by DbH was studied by HPLC and some oxidation products for 1 could be characterized. The compounds generally observed with iron-containing systems are 4-methoxyphenylurea 11 and 4-methoxyphenylcyanamide 12 (Fig. 2). Oxidation of N-(4-chlorophenyl)-N′-hydroxyguanidin

Recently, naphthoquinone derivatives have shown promising results as antiparasitic lead compounds [28]. Conjugated hybrid compounds could be an effective path to discovery of new drugs by associating two different pharmacophore groups with different mechanisms of action in a single molecule [29,30],
