Gum kondagogu (GK), a natural biopolymer was successfully employed in the synthesis of trimetallic (AgAuPd) nanocomposites and characterized for their physicochemical properties in comparison with the monometallic nanoparticles. The UV–visible spectrum of GK-Ag nanoparticles (NPs) and GK-AuNPs showed distinctive surface plasmon peaks at 418 and 546...

Silver-containing materials have been the source of attraction due to their excellent optical and photocatalytic properties. Silver vanadium phosphate, Ag2VO2PO4, (hereafter abbreviated as AVP) in nanorods form was synthesized by hydrothermal method at 220 °C for 24 h and characterized by PXRD, FT-IR, ³¹P MAS NMR, SEM-EDS, TEM-SAED, N2 adsorption-d...

Cervical cancer (CC) constitutes about 70%–80% of squamous cell carcinoma and 10%–15% of adenocarcinoma. In about 90% of CC cases the Human papillomavirus (HPV) infection appears to be the main culprit. Other risk factors include smoking, compromised immune system, birth control pills, starting sex at a young age, and having many sexual partners. I...

Bimetallic nanoparticles (BNPs) constitute two different metal elements and exhibit relatively superior mechanistic and catalytic efficacies owing to their synergistic functions over monometallic nanoparticles. In the present study various bimetallic Ag-Au, Ag-Pd, Au-Pd nanoparticles were synthesized using a natural biopolymer gum kondagogu (GK) as...

Phytomedicine is a plant-based medicinal system involved in preventive, healing, and therapeutic procedures. The plant or botanical sources are acknowledged to deliver various modules or chemical entities for therapeutic, pharmacological, and nutritional requirements such as drugs, nutraceuticals (functional foods), proteins, and gum resins. Plant-...

Novel antimicrobial agents with a low propensity to develop resistance by microorganisms have contemporary relevance. In this perspective, the present study reports the green synthesis and characterization of cecropins peptides (D2A21, D2A10, and D4E1) based silver nanocomposites. The effect of pH and concentration of peptides on the formation of n...

Andrographis paniculata and Coleus forskholii are medicinal plants, used in traditional Ayurveda systems and owe therapeutic properties due to their bioactive ingredients andrographolide and forskolin respectively. In the present investigation, both these molecules were evaluated at a dose of 10 mg kg⁻¹ body mass administered by gavage, for their a...

Abstract: Background: Forskolin and Andrographolide are extensively used in many parts of Asia as traditional herbal medicines. Potato tumor bioassay has several advantages for pre-screening of anti-tumor molecules as compared to animal cell based bioassays. The present study was aimed to evaluate the antitumor potential, biochemical changes induce...
