W1282X is the fifth most common CFTR mutation that causes cystic fibrosis. Here, we investigated the utility of a small molecule corrector / potentiator strategy, as used for ΔF508-CFTR, to produce functional rescue of the truncated translation product of the W1282X mutation, CFTR1281, without the need for read-through. In transfected cell systems, certain potentiators and correctors including VX-809 and VX-770 increased CFTR1281 activity. To identify novel correctors and potentiators with potentially greater efficacy on CFTR1281, functional screens were done of ~30,000 synthetic small molecules and drugs/nutraceuticals in CFTR1281-transfected cells...

Solvent free mechanochemical approach is utilized to synthesise new cocrystals of chrysin using supramolecular chemistry based upon reliable synthons. Chrysin, a flavone nutraceutical with wide range of beneficial effects has critically low bioavailability on account of its poor aqueous solubility and consequently poor absorption from the gastrointestinal tract. The present study focuses on this critical aspect and has exploited non covalent interactions to prepare its cocrystals with cytosine and thiamine hydrochloride...

REVIEW
Jürg Gertsch
The endocannabinoid system (ECS) is a major lipid signaling network that plays important pro-homeostatic (allostatic) roles not only in the nervous system but in peripheral organs. Increasing evidence points towards a dietary component in the modulation of the ECS. Cannabinoid receptors in hominids co-evolved with diet and the ECS constitutes a feedback loop for food selection and energy metabolism. Here it is postulated that the mismatch of ancient lipid genes of hunter-gatheres and pastoralists with the high carbohydrate diet introduced by agriculture could be compensated via dietary modulation of the ECS...

BACKGROUND: Depressive episodes and cognitive impairment are major causes of morbidity and dysfunction in individuals suffering from bipolar disorder (BD). Novel treatment approaches that target clinical and cognitive aspects of bipolar depression are needed, and research on pathophysiology suggests that mitochondrial modulators such as the nutraceutical creatine monohydrate might have a therapeutic role for this condition. METHODS: Eighteen (N=18) patients with bipolar depression according to DSM-IV criteria who were enrollled in a 6-week, randomized, double-blind, placebo-controlled trial of creatine monohydrate 6g daily as adjunctive therapy were submitted to neuropsychological assessments (Wisconsin Card Sorting Test, Digit Span subtest of the Wechsler Adult Intelligence Scale-Third Edition, Stroop Color-Word Test, Rey-Osterrieth complex figure test, FAS Verbal Fluency Test) at baseline and week 6...
