    Synthesis, biological evaluation and in-silico ADME studies of novel series of thiazolidin-2,4-dione derivatives as antimicrobial, antioxidant and anticancer agents
    (BioMed Central Ltd, 2022-09-15T00:00:00) Kumar, Harsh; Kumar, Davinder; Kumar, Pradeep; Thareja, Suresh; Marwaha, Minakshi Gupta; Navik, Umashanker; Marwaha, Rakesh Kumar
    Background: A novel series of thiazolidine-2,4-dione molecules was derived and their chemical structures were established using physiochemical parameters and spectral techniques (1H-NMR, IR, MS etc.). The synthesized molecule were then evaluated for their antioxidant, anticancer and antimicrobial potential. Results and discussion: Serial tube dilution method was employed to evaluate the antimicrobial potential against selected fungal and bacterial strains by taking fluconazole and cefadroxil as reference antifungal and antibacterial drugs respectively. 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity was used to assess the antioxidant potential of the synthesized analogues. Further, the anticancer potential of the selected molecules was assessed against DU-145 cancer cell lines using MTT assay. The drug-likeness was also evaluated by studying in-silico ADME parameters of the synthesized analogues. Conclusion: In antioxidant evaluation studies, the analogue H5 with IC50 = 14.85�?g/mL was found to be the most active molecule. The antimicrobial evaluation outcomes suggested that the molecules H5, H13, H15 and H18 possessed moderate to promising activity against the selected species of microbial strains having MIC range 7.3��M to 26.3��M. The results of anticancer evaluation revealed that all the screened derivatives possess mild anticancer potential. The in-silico ADME studies revealed that all the compounds were found to be drug-like. � 2022, The Author(s).

    Transcriptome characterization and generation of marker resource for Himalayan vulnerable species, Ulmus wallichiana
    (Springer Science and Business Media B.V., 2021-01-14T00:00:00) Singh, Amandeep; Majeed, Aasim; Bhardwaj, Pankaj
    Ulmus wallichiana is a traditional medicinal plant listed as a vulnerable in the IUCN red list data. Genomic and transcriptomic resources for this species are lacking, hindering its genetic exploration. Further, no polymorphic marker resource is available for this species, thus limiting the elucidation of its underlying genetic diversity, which is a pre-requisite for its conservation. This study was therefore aimed to generate a functionally annotated transcriptomic resource and screen it for SSR regions. We used paired-end Illumina based RNAseq technology and trinity based de novo assembly approach to generate full length transcripts, which were screened for SSR regions and functionally annotated. Around 6.6 million raw reads were de novo assembled transcripts, which were clustered into 146,083 unigenes. 19,909 transcripts were provided with 3986 unique KEGG ids, 70,519 transcripts with 6621 unique Pfam domains, and 45,125 transcripts with 7302 unique INTERPRO domains. 1456 transcripts were identified as transcriptions factors (TFs). Further, 8868 unique GO terms were obtained for the unigenes. The transcripts mapped to 23,056 known pre-determined orthology clusters in the eggNOG database. A total of 16,570 SSRs were identified from the unigenes. Out of the 90 SSRs selected for characterization on 20 genotypes, 28 were polymorphic. Mean effective alleles (Ne) of 2.53, mean observed heterozygosity (Ho) of 0.77, and average polymorphic information content (PIC) of 0.57 were found. This study may facilitate the genetic exploration of this species. The polymorphic SSRs would prove useful to explore its genetic diversity patterns, required for its conservation. � 2021, The Author(s), under exclusive licence to Springer Nature B.V. part of Springer Nature.

    Correlation of microscopic interaction with electrical conductivity in polymer separator of energy storage devices
    (Springer Science and Business Media, LLC, 2017) Sharma, Parul Kumar; Sharma, Anshul Kumar; Sadiq, M.; Sharma, A. L.
    In the present report solid polymer nanocomposite (PNCs) comprising of (PEO)14+ NaClO4+ wt% BaTiO3has been prepared by solution casting method. Important characterization like: FTIR (Fourier Transform Infrared Spectroscopy), and conductivity have been performed for the applicability of the prepared materials in device application. The highest conductivity of the prepared polymer nanocomposite materials has been estimated 1?10?4Scm?1for 15 wt% of BaTiO3. A very fine correlation has been built among polymer-ion, ion-ion and polymer ion interaction with obtained conductivity results. ? Springer International Publishing Switzerland 2017.
