Insulin amyloid fibril formation reduction by tripeptide stereoisomers
A simple tripeptide significantly reduces insulin amyloid fibril formation and it is proposed as a formulation stabiliser. In silico studies reveal the mechanism of interaction with the insulin hydrophobic motifs that are prone to fibrillation.
Engineered nanomicelles targeting proliferation and angiogenesis inhibit tumour progression by impairing the synthesis of ceramide-1-phosphate
Tumour cells secrete various proangiogenic factors like VEGF, PDGF, and EGF that result in the formation of highly vascularized tumours with an immunosuppressive tumour microenvironment.
Relative biomembrane fusogenicities of the tumor-selective liposomes of RGDK- and CGKRK-lipopeptides
Both the FRET assay using model biomembranes and cellular uptake studies revealed a higher membrane fusogenic nature of the tumor-targeting liposomes of the RGDK-lipopeptide than that of the tumor-targeting liposomes of the CGKRK-lipopeptide.
Rapid targeting and imaging of mitochondria via carbon dots using an amino acid-based amphiphile as a carrier
Green-fluorescent, negatively charged newly synthesized carbon dots cannot penetrate KB and CHO cell lines. But, an amino acid containing amphiphile with a positively charged group forms an aggregate that acts as a carrier for these carbon dots for cell entry and to label and image mitochondria.
Nanoscale assembly of enantiomeric supramolecular gels driven by the nature of solvents
Different co-assembly modes depending on the nature of the solvents observed in multi-component systems with structurally similar components.
Self-assembly of water-filled molecular saddles to generate diverse morphologies and high proton conductivity
A saddle that protons can ride on! A saddle-shaped aza-crown-like macrocycle produces diverse morphologies and high solid-state proton conduction up to 21.1 mS cm−1 (at 27 °C and 95% RH).
Nanoparticle-mediated co-delivery of inflammasome inhibitors provides protection against sepsis
A dual-drug loaded nanoparticle demonstrates superior inhibition of NLRP3 inflammasome activation and improves the survival rate in a mouse model of septic peritonitis.
Sugar alcohol-modified polyester nanoparticles for gene delivery via selective caveolae-mediated endocytosis
Sugar alcohol-modified poly(β-amino esters) enables selective caveolae-mediated endocytosis.
Cooperative dissolution of peptidomimetic vesicles and amyloid β fibrils
Cooperative dissolution of drug-loaded peptidomimetic vesicles and amyloid β (Aβ) fibrils allows for the development of therapeutic formulations to modulate disorders associated with amyloid toxicity.
Post-functionalization of sulfur quantum dots and their aggregation-dependent antibacterial activity
Sulfur quantum dots (SQDs) exhibited potent antibacterial activity upon surface functionalization. Yet, hydrophobic ligand attachment diminished efficacy. This study underscores the impact of hydrophobicity on antibacterial agent development.
About this collection
Professor Bhattacharya obtained his PhD with Professor Robert A. Moss at Rutgers University, USA, and had a post-doctoral stint with Nobel Laureate Professor Har Gobind Khorana at MIT, USA. He has been working at the Indian Institute of Science since 1991 and is an honorary professor at the Chemical Biology Unit of the Jawaharlal Nehru Centre for Advanced Scientific Research, Bangalore, India.
