Journal ArticleDOI
Metal-free triplet phosphors with high emission efficiency and high tunability.
Michael Koch,Karthikeyan Perumal,Olivier Blacque,Jai Anand Garg,Ramanathan Saiganesh,Senthamaraikannan Kabilan,Kallupattu Kuppusamy Balasubramanian,Koushik Venkatesan +7 more
TL;DR: Design of highly efficient phosphorescent emitters based on metal- and heavy atom-free boron compounds has been demonstrated by taking advantage of the singlet fission process.
Journal ArticleDOI
β-Iminoenamine-BF2 complexes: aggregation-induced emission and pronounced effects of aliphatic rings on radiationless deactivation.
Karthikeyan Perumal,Jai Anand Garg,Olivier Blacque,Ramanathan Saiganesh,Senthamaraikannan Kabilan,Kallupattu Kuppusamy Balasubramanian,Koushik Venkatesan +6 more
TL;DR: For most of the studied compounds, time-dependent DFT (TD-DFT) calculations invariably reveal intramolecular charge transfer (π-π*) characteristics with the frontier orbitals concentrated on the boron-nitrogen heterocycle.
Journal ArticleDOI
Evaluation of antioxidant, antimicrobial and antiproliferative activity of silver nanoparticles derived from Galphimia glauca leaf extract
Bidhayak Chakraborty,Raju Suresh Kumar,Abdulrahman I. Almansour,D. Kotresha,Muthuraj Rudrappa,S S Pallavi,Halaswamy Hiremath,Karthikeyan Perumal,Sreenivasa Nayaka +8 more
TL;DR: In this paper, green synthesis and characterizations of AgNPs from G. glauca leaf extract and evaluation of their bioactive potential were performed and the first indication of synthesis of nanoparticles was the change in color from yellowish to brown.
Journal ArticleDOI
A competent synthesis and efficient anti-inflammatory responses of isatinimino acridinedione moiety via suppression of in vivo NF-κB, COX-2 and iNOS signaling.
Govindasami Periyasami,Paulrayer Antonisamy,Karthikeyan Perumal,Antony Stalin,Mostafizur Rahaman,Asma A. Alothman +5 more
TL;DR: It was found that the treatment with the synthesized isatinimino analogues (dosage: 30 mg/kg) inhibited protein expression of cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), and nuclear factor kappa B (NF-κB) as well as production of prostaglandin E2 and interleukin-6 levels induced by carrageenan.
Journal ArticleDOI
Domino Multicomponent Approach for the Synthesis of Functionalized Spiro-Indeno[1,2-b]quinoxaline Heterocyclic Hybrids and Their Antimicrobial Activity, Synergistic Effect and Molecular Docking Simulation.
Abdulrahman I. Almansour,Natarajan Arumugam,Raju Suresh Kumar,Dhaifallah M. Al-thamili,Govindasami Periyasami,Karuppiah Ponmurugan,Naif Abdullah Al-Dhabi,Karthikeyan Perumal,Dhanaraj Premnath +8 more
TL;DR: The synergistic effect revealed that the combination of compound 8h with streptomycin and vancomycin exhibited potent synergistic activity against E. coli ATCC 25922.
