A progression of fourteen narrative quinolonyl diketo acid analogs were planned, synthesized, identified by IR, NMR, CHN and MS supernatural analysis and evaluated as potential HIV-1 Integrase hinders. Compounds of Zinc database were surfed considering Elvitegravir as standard. Nearly 99 compounds were identified and docked in the active site of HIV-1 integrase. Molecular docking study of compounds 1, 4 and 7 showed docking score -10.38, -9.31 and -10.12 respectively as that of set drug Elvitegravir -4.93. The docking poses to open the interaction of the ligands with preferred amino acids. The standard drug Elvitegravir displayed connections with lys156, Asn155, Lys159 and Thr66. Raltegravir showed hydrogen bonding with Asp 116. A round fourteen target diketoquinolines were chosen for advance synthesis with the help of substituted oxoquinoline-3-carboxylate as starting material. In-vitro biological evaluation open that some of the upper-class compounds exhibited moderate to good inhibitory activity besides HIV1 Integrase compared to the reference drugs Raltegravir and Nevirapine. Compounds 1, 2, 3 and 4 weakly inhibited HIV-1 integrase at EC50 of 0.31,...

Dairy and milk consumption are habitually included as important essentials in a healthy and balanced diet. It is the principal food for mammals and provides all the essential energy and nutrients to guarantee proper growth and development. Whey protein present in the milk is quickly digested and therefore amino acids are delivered quickly to muscles to help start the muscle-building process. The major components of milk whey of nutraceutical potential include beta-lactoglobulin, alpha-lactalbumin, bovine serum albumin (BSA), lactoferrin (Lf), immunoglobulin’s (Igs), lactoperoxidase (Lp) enzymes, glycomacropeptides (GMP), lactose and minerals. The main aim of this study is to determine the antimicrobial and antioxidant activity of whey protein concentration from cow’s milk. The result of the present study reveals the fact that the whey milk exhibited good antimicrobial activity. Whey protein α – lacto albumin and β – globulin were confirmed by two peaks with the retention time of 3.96 and 9.45. Thus, HPLC confirmed the presence of protein in the whey milk...

In the present study novel matrix diffusion controlled transdermal patches of Hydralazine hydrochloride, a hypertensive drug to ensure satisfactory drug release were successfully prepared by solvent casting method with optimization of suitable polymeric blend of Eudragit L100 (EL-100), ethyl cellulose (EC), polyvinylpyrrolidone (PVP), polyvinyl alcohol (PVA), carbopol, hydroxypropyl cellulose (HPC) to achieve sustained release pattern within the therapeutic range. N-dibutyl phthalate (n-DB) used as a plasticizer and oleic acid used as a permeation enhancer. Different batches of transdermal patches were prepared by varying different polymers with the difference in ratio. Prepared transdermal patches from each batch, gave release profile for over 12 h. Fourier Transform Infrared analysis shows no interaction between drugs and polymers. Cumulative amount of drug release in 12 h from all the prepared formulation were found to be in following order: F1> F2> F3> F4> F9> F8> F7> F10> F5.F6. Combination of Eudragit L100 and PVP (F1 and F2) and Ethylcellulose and PVP (F3 and F4) exhibited good characteristics for sustained release...

Inflammation is a normal, protective response to tissue injury caused by physical trauma, noxious chemicals or microbiological agents. Medicinal plants and their secondary metabolites are progressively used in the treatment of diseases as complementary medicine. In the present study methanolic extract of flower heads of Tagetes erecta was screened for its phytochemical constituents and then subjected for its anti-inflammatory activity by using in-vitro and in-vivo methods. The preliminary phytochemical investigation of methanolic extract of flower heads of Tagetes erecta showed the presence of flavonoids like quercetin, kaempferol, gallic acid, syringic acid, terpenoids like β-amyrin, erythrodiol, steroids like β-sitosterol, β-stigmasterol, phenols, and alkaloids. The methanolic extract of Tagetes erecta (METE) significantly (p<0.05) inhibited the paw oedema volume. The extract significantly (p<0.05) protected protein membranes from denaturation. To understand the ligand-binding affinity of the above constituents with COX-2 the constituents were subjected to molecular docking studies using ligand fit of maestro 9.1 (Schrodinger Software Inc.). Amongst the constituents identified kaempferol, quercetin, gallic acid were found to possess strong binding affinity towards...

The pigment has acquired the greatest importance because of its excellent color value. The potential use of various carbon sources as microbial pigments for textile coloration. Flowers, leaves, fruits, vegetables, and tubers are the rich source of the secondary metabolites. In the current study, the use of microbial extract isolated from a fermentation process from 14 varieties by using Penicillium purpurogenum as a natural dye was studied. The potentiality of the dye extract was classified by dyeing with 100% cotton under suitable conditions. The dye ability, colorfastness (wash, light, rubbing) and Munsell color value, hue, L, a, b of dyed liquids were studied by using computer color matching software were studied. The color of the dye was not affected by washing. The results reveal that Hibiscus rosa sinensis, Ixora coccinea and Nerium oleander having highest K/S values. It could be seen that P. purpurogenum responded by producing high concentrations of pigment from Tagetes patula flower (crude) than the other combinations. It is to their ability for the formation of...
