Amino Acid-Porphyrin Conjugates: Synthesis and Study of their Photophysical and Metal Ion Recognition Properties

Paul, A K; Suneesh, C K; Joseph, J; Ramaiah, D (Elsevier, 2015-11)

Synthesis, photophysical and metal ion recognition properties of a series of amino acid-linked free-base and Zn-porphyrin derivatives (5–9) are reported. These porphyrin derivatives showed favorable photophysical properties ...
Antimicrobial photodynamic efficiency of novel cationic porphyrins towards periodontal gram-positive and gram-negative pathogenic bacteria

Prasanth, C S; Suneesh, C K; Albish, K P; Kussovski, V; Mantareva, V; Ramaiah, D; Selvaraj, L; Angelov, I; Avramov, L; Nandakumar, K; Subhash, N (John Wiley, 2014)

The Gram-negative Aggregatibacter actinomycetemcomitans and Fusobacterium nucleatum are major causative agents of aggressive periodontal disease. Due to increase in the number of antibiotic-resistant bacteria, antimicrobial ...
In Vitro Demonstration of Apoptosis Mediated Photodynamic Activity and NIR Nucleus Imaging through a Novel Porphyrin

Suneesh, C K; Saneesh Babu, P S; Madhuri, B; Betsy, M; Albish, K P; Asha S Nair; Sridhar Rao,K; Srinivasan, A; Chandrashekar, T K; Mohan Rao, Ch; Radhakrishna Pillai; Ramaiah, D (American Chemical Society, 2013)

We synthesized a novel water-soluble porphyrin THPP and its metalated derivative Zn-THPP having excellent triplet excited state quantum yields and singlet oxygen generation efficiency. When compared to U.S. Food and Drug ...
Photoinduced DNA damage efficiency and cytotoxicity of novel viologen linked pyrene conjugates

Mahesh Hariharan; Suneesh, C K; Ramaiah, D; Schulz, I; Epe, B (Royal Society of Chemistry, 2010)

Novel viologen linked pyrene conjugates permeate cells efficiently and exhibit spacer length dependent DNA damage and cytotoxicity upon photoexcitation.
Selective recognition of tryptophan through inhibition of intramolecular charge-transfer interactions in an aqueous medium

Mahesh Hariharan; Suneesh, C K; Ramaiah, D (American Chemical Society, 2007)

A novel donor-acceptor conjugate 1 was synthesized, and its interactions with various amino acids have been investigated as compared to the model system 2. The conjugate 1 unusually forms an intramolecular charge-transfer ...
