Antibacterial and synergy potential of naturally occurring indole alkaloids (IA): 10-methoxy tetrahydroalstonine (1), isoreserpiline (2), 10 11 demethoxyreserpiline (3), reserpiline (4), serpentine (5), ajmaline (6), ajmalicine (7), yohimbine (8), α-yohimbine (9) was evaluated using microbroth dilution assay. Further, chemically transformed into six semisynthetic derivatives (9A-9F), their antibacterial in combination with nalidixic acid (NAL) against E. coli strains CA8000 DH5α were also...

Although a number of chemicals have been isolated from Lantana camara, only few evaluated for their biological significance. As part our drug discovery program cytotoxic agents Indian medicinal plants, roots L. camara were chemically investigated, which resulted in the isolation and identification agent, oleanolic acid (1b) as major constituent. Oleanolic was converted into six semi-synthetic ester (2-7) seven amide (8-14) derivatives. The derivatives showed 3-6 times more selective activity...
pH‐zone‐refining centrifugal partition chromatography was successively applied in the large‐scale separation of close R f antipsychotic indole alkaloids directly from CHCl 3 fraction auwolfia tetraphylla leaves. Two experiments with increasing mass 500 mg to g crude alkaloid extracts ( 1 C ) . were carried out normal‐displacement mode using a two‐phase solvent system composed methyl tert‐butyl ether/ ACN /water (4:1:5, v/v/v) where HCl (12 mM) added lower aqueous stationary phase as retainer...
Volatile essential oils from Prinsepia utilis L. have been shown to inhibit stomatal opening in Vicia faba epidermal peels as well whole leaves by measurement of pore width and conductance (gs). The closure was associated with inhibition K+ influx the guard cells. Gas chromatography/mass spectroscopy analysis steam distillate P. showed presence over twenty compounds; which thirteen compounds identified.
Two bioactive constituents, khusenic acid (1) and khusimol (2), were isolated characterized from hexane fraction of Vetiveria zizanoides roots. Compounds, 1 2, tested against the various drug-resistant mutants Mycobacterium smegmatis. The results showed that compound was 4 times more active than standard drugs ciprofloxacin (CF) nalidixic (NA) (CSC 101) lomefloxacin(LOMR5)-resistant mutants, whereas 2 CSC 101 NA CF. Further, these compounds virulent strain H37Rv tuberculosis, which two NA,...
Abstract With mental health needs consistently increasing in our communities and medical centers, we want to ensure that institutions are aware of the benefit value psychologists bring their system provide several pathways for consideration structure understand how support salaries careers working within AHCs. Leadership administration Academic Health Centers (AHC) often do not measurement productivity being added teams. The current article aims present varied structural models demonstrate...
Fast centrifugal partition chromatography was successfully applied in the separation of bioactive constituent niazirin directly from chloroform extract Moringa oleifera. The experiment performed with a two-phase solvent system composed ethyl acetate/BuOH/water (6:0.5:4 v/v/v) which upper organic layer used as stationary phase and lower aqueous mobile phase. From 1 g crude extract, 70 mg obtained 94.8% purity determined by HPLC. total yield recovery >94%. isolated nitrile glycoside (niazirin)...
A simple isocratic HPLC method has been developed for the simultaneous quantitation of three antipsychotic indole alkaloid (IA), α-yohimbine (1), isoreserpiline (2), and 10-methoxy tetrahydroalstonine (3) in Rauwolfia tetraphylla leaf. Samples were analyzed by reverse-phase chromatography on a Waters spherisorb ODS2 column using elution with acetonitrile containing 0.1% TEA water TFA (35:65, v/v) at flow rate 1 mL/min, temperature 30°C, UV detection 210 nm. The was validated applied...
The world is witnessing a stupendous rise in Environmental, Social, and Governance (ESG) investment practices due to changing dimensions of risks consequent clamour for the adoption sustainable practices. In this scenario, ESG-themed mutual funds have provided an alternative route ESG investing. This study aims analyse growth India evaluate their performance using standalone return risk measures as well widely recognised risk-adjusted measures, namely, Sharpe Index, Treynor Ratio, Sortino...
<p>Recent innovations in the telecommunication have proven to be a boon for banking sector and its customers: One of these is Mobile Banking, where customers interact with bank via mobile phones banks provide them services like short message services, fund transfers, account details, issue cheque book etc. Presently almost all world started providing their "Mobile Banking" services. The main this study understand factors which contribute user's intention use purpose review paper...
A quest for sustainable development has propelled investors and corporates to adopt environmental, social, governance (ESG) philosophy in their investment business decisions. In this scenario, ESG scores appear be an indicator of the performance a firm. The present study seeks compare practices 100 top companies (by market capitalization) across 10 sectors India. For analysis, CRISIL’s overall each its dimensions have been used. Application oneway ANOVA Welch reveals that there exist...
Abstract: The Internet of things has gained intense popularity in the past few years. It become one most important technologies. However along with gaining popularity, threats related to cyber security have increased. As name suggests, Things, it is completely based on internet which means a hacker can find weaklink network and exfiltrate data cloud threaten keep, delete or make public. Thisincludes sensitive data, personally identifiable information (PII), protected health (PHI), personal...
