Hydroxytriazenes incorporating sulphonamide derivatives: evaluation of antidiabetic, antioxidant, anti-inflammatory activities, and computational study.

The existent investigation deals with synthesis, characterization, computational analysis, and biological activities of some hydroxytriazene derivatives containing sulphonamide moiety. The compounds were screened for antidiabetic, antioxidant, and anti-inflammatory activities. The antidiabetic activity was assessed using α-glucosidase and α-amylase inhibition assays with IC50 values ranging from 32.0 to 759.13 µg/mL and 157.77 to 340.47 µg/mL while standard drug acarbose showed IC50 values 12.21 and 69.74 µg/mL, respectively. The antioxidant activity was evaluated using DPPH and ABTS radical scavenging assays with IC50 value ranging from 54.01 to 912.66 µg/mL and 33.22 to 128.11 µg/mL, and standard drug ascorbic acid showed IC50 values 29.12 µg/mL and 69.13 µg/mL, respectively. Anti-inflammatory activity was investigated using the carrageenan-induced paw edema method, where percentage inhibition was up to 93.0 and 98.57 for 2 h and 4 h, respectively, and all the compounds were found to exhibit excellent anti-inflammatory activity. Moreover, prediction of activity spectra for substance and molecular docking were also performed. The PASS prediction hypothesized the potential of the compounds for anti-inflammatory activity, and docking results suggested the best binding pose for compounds 1b and 2b with the least energy value from which compounds can be considered as potent COX-2 inhibitors. Furthermore, possible interactions between hydroxytriazene analogues and the targets of antioxidant NADPH oxidase and antidiabetic human maltase-glucoamylase enzyme have been identified. The HOMO and LUMO analysis revealed charge transfer within the compounds. These findings suggested that the synthesized compounds can be potential agents for the treatment of diabetes and inflammation.

AFLP markers based genetic diversity and population structure analysis of Kadaknath: an indigenous black meat poultry breed of India.

The current study is the first worldwide to assess the genetic diversity of Kadaknath poultry using amplified fragment length polymorphism (AFLP) markers. Out of total 96 accessions, four were outliers and 92 were Kadaknath accessions of which 30 were males, 62 were females. Of these, 74 were jet black, 7 penciled and 11 were golden feather color type of Kadaknath. High level of polymorphism (23.94%) was observed in 387 loci amplified using six AFLP primer combinations. The Jaccard's similarity coefficient ranged from 0.211 to 0.754 with an average dissimilarity of 0.517. Based on the neighbor-joining method of clustering, all accessions were clustered into seven major clusters which were not consistent with their respective geographical locations. The mean values of effective multiplex ratio, polymorphic information content, resolving power and marker index were 15.16, 0.38, 9.87 and 5.85 respectively. Further, the high log-likelihood score was produced when the number of populations (K) was set at 7 while carrying out the population STRUCTURE analysis, which was also congruent with clustering analysis based on genetic diversity. The extent of genetic diversity detected in this study could be used for germplasm selection and developing conservation strategies of pure breed of Kadaknath.

An Emerging Role for Understanding Orthostatic Hyp'er'tension in the Cardiorenal Syndrome.

Orthostatic hypertension (OHT) is a clinically important problem increasingly recognized in persons with borderline hypertension, diabetes mellitus, and autonomic neuropathies, and in the elderly. Moreover, the association of OHT with progression of target end-organ damage, especially coronary heart disease and chronic kidney disease (CKD), and the attendant increased cardiovascular disease (CVD) and CKD risk, is gaining attention but is still underappreciated. There are various mechanisms that contribute to the development of OHT: excessive vascular adrenergic sensitivity, baroreceptor reflex abnormalities, and inappropriate activation of the renin-angiotensin-aldosterone system, which are also mechanisms that lead to cardiorenal metabolic disease (CRS). While the evidence is compelling for the clinical importance of OHT, more investigation is needed to evaluate the effects of OHT on CKD and CVD. The notion that the development of OHT is a risk factor for the development of CRS raises the need for further clinical and investigational attention to this clinical dilemma.
