Use of human tissue in ADME and safety profiling of development candidates

The clinical success of a compound is often curtailed because of inadequate safety, pharmacokinetics or efficacy. Human tissue can be used to identify the potential shortcomings of new drugs before they undergo testing in man. This review highlights the consent and ethical approval required for the use of human tissues and discusses their use for predicting human ADME and safety profiles of drugs in preclinical development. The ability to retrieve a wide range of viable tissues from human donors provides the opportunity to test drugs for many potential use-limiting side-effects.

On the influence of chiral auxiliaries in the stereoselective cross-coupling reactions of titanium enolates and acetals

Titanium enolates from chiral N-propanoyl-1,3-thiazolidine-2-thiones containing bulky substituents at C4 turned out to be excellent platforms to get highly stereocontrolled cross-coupling reactions with acetals. Related oxazolidinethiones also afforded good results, but the corresponding oxazolidinones resulted completely unselective for such reactions, which proves that an exocyclic C{double bond, long}S bond is essential to attain a synthetically useful stereocontrol.

The zebrafish Kupffer’s vesicle as a model system for the molecular mechanisms by which the lack of Polycystin-2 leads to stimulation of CFTR

In autosomal dominant polycystic kidney disease (ADPKD), cyst inflation and continuous enlargement are associated with marked transepithelial ion and fluid secretion into the cyst lumen via cystic fibrosis transmembrane conductance regulator (CFTR). Indeed, the inhibition or degradation of CFTR prevents the fluid accumulation within cysts. The in vivo mechanisms by which the lack of Polycystin-2 leads to CFTR stimulation are an outstanding challenge in ADPKD research and may bring important biomarkers for the disease. However, hampering their study, the available ADPKD in vitro cellular models lack the three-dimensional architecture of renal cysts and the ADPKD mouse models offer limited access for liveimaging experiments in embryonic kidneys. Here, we tested the zebrafish Kupffer’s vesicle (KV) as an alternative model-organ. KV is a fluid-filled vesicular organ, lined by epithelial cells that express both CFTR and Polycystin-2 endogenously, being each of them easily knocked-down. Our data on the intracellular distribution of Polycystin-2 support its involvement in the KV fluid-flow induced Ca2+ -signalling. Mirroring kidney cysts, the KV lumen inflation is dependent on CFTR activity and, as we clearly show, the knockdown of Polycystin-2 results in larger KV lumens through overstimulation of CFTR. In conclusion, we propose the zebrafish KV as a model organ to study the renal cyst inflation. Favouring its use, KV volume can be easily determined by in vivo imaging offering a live readout for screening compounds and genes that may prevent cyst enlargement through CFTR inhibition.

Antioxidants and chronic obstructive pulmonary disease

Antioxidants represent an attractive therapeutic avenue for individuals with chronic obstructive pulmonary disease (COPD). Cigarette smoke, the major cause of COPD, contains very high concentrations of gaseous and soluble oxidants that can directly induce cell injury and death. Furthermore, particulate matter in cigarette smoke activates lung macrophages that subsequently attract neutrophils. Both neutrophils and macrophages from the lungs of cigarette smokers continuously release large amounts of superoxide and hydrogen peroxide through the nicotinamide adenine dinucleotide phosphate (NADPH) oxidase complex. Once individuals with COPD stop smoking, the neutrophilic inflammation in the airways and lung parenchyma persists, as do the markers of oxidative stress. Several animal models of cigarette smoke-induced injury have provided evidence that various antioxidants may prevent inflammation and morphological changes associated with COPD however, evidence of benefit in patients is less abundant. Although oxidants can inactivate alpha-1 antitrypsin and other protective proteins, damage lung tissue, and increase mucus production, they also are essential for killing pathogens and resolving inflammation. This review will examine the pre-clinical and clinical evidence of a role for antioxidants in the therapy of patients with COPD.

Pharmacological therapy for acute respiratory distress syndrome

Acute respiratory distress syndrome (ARDS) is an inflammatory process caused by a variety of direct and indirect injuries to the lungs. Despite improvements in supportive care and advances in ventilator management, mortality in patients with ARDS remains high. Multiple pharmacological interventions have been investigated but have not shown improved survival. Clinical trials using corticosteroids, prostaglandins, nitric oxide, prostacyclin, surfactant, lisofylline, ketoconazole, N-acetylcysteine, and fish oil have been unable to show a statistically significant improvement in patient mortality. As more is understood about the pathophysiology of ARDS, treatment strategies statistically as increasing alveolar fluid clearance through activation of sodium channels, enhancing repair of alveolar epithelium with growth factors, inhibiting fibrin deposition, blocking proinflammatory transcription factors, preventing the effect of potent vasocontrictors such as endothelin, and using antibodies against key inflammatory cytokines are being explored. This review focuses on the pharmacological treatments studied clinically, proposed reasons for their lack of success, and new concepts emerging in ARDS therapy.

Anti-diabetic and anti-hyperlipidemic effects of 2-[(Trimethylsilyl)-oxy]-, trimethylsilyl ester isolated from Pericampylus glaucus in diabetic rats

The purpose of the present study was to isolate and identify 2-[(trimethylsilyl)-oxy]-, trimethylsilyl ester compound from Pericampylus glaucus and to evaluate their effects on blood glucose and lipid profiles in diabetic rats. The isolation and identification of compound 2-[(trimethylsilyl)-oxy]-, trimethylsilyl ester was undertaken through column chromatography followed by GCMS and1HNMR. The anti-hyperglycemic effect of isolated compound was carried out against STZ-induced diabetic rats. GC followed by MS and1HNMR indicate the presence of compound 2-[(trimethylsilyl)-oxy]-, trimethylsilyl ester in sample. The weight was 234, retention time 2.99, and total area was 1015482. The compound significantly (P < 0.01) reduced blood glucose level in hyperglycemic rats as matched to control. The attenuation on blood glucose level with 2-[(trimethylsilyl)-oxy]-, trimethylsilyl ester were non-significant (P > 0.05) up to 4 h that became significant (P < 0.01) at 24 h as matched to diabetic group. A significant (P < 0.001) attenuation in levels of cholesterol, triglycerides, LDL and significant (P < 0.01) increased in HDL was noted in 2-[(trimethylsilyl)-oxy]-, trimethylsilyl ester treated group. The findings of this study indicate that isolated compound Pericampylus glaucus compound 2-[(trimethylsilyl)-oxy]-, trimethylsilyl ester has significant attenuation effect on blood glucose and lipid profiles. Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: Thiazolidin-2-one, you can also check out more blogs about2682-49-7
