Synthesis of bisindolylmethanes and their cytotoxicity properties Kalla Naidu, Shaik Khalivulla, Syed Rasheed, Sharida Fakurazi, Palanisamy Arulselvan, et al. International Journal of Molecular Sciences, 2013 Polymer supported dichlorophosphate (PEG-OPOCl2) is an efficient green catalyst for the electrophilic substitution reaction of indole with aromatic aldehydes, in neat condition, to afford an excellent yield of bis(indolyl) methanes with short reaction time, at room temperature. The synthesized compounds and their anti-cancer activity are evaluated.
Headspace solid-phase microextraction gas chromatography-mass spectrometry and gas chromatography-olfactometry analysis of volatile compounds in pineapple breads Saw Ying, Ola Lasekan, Kalla Naidu, Seye Lasekan Molecules, 2012 Sensorial analysis of pineapple breads (conventionally baked, Cpb; fully baked frozen, Fpb and partially baked, Ppb) showed no significant differences in terms of aroma and taste. On the contrary, the scores for the overall quality between the partially baked and conventionally baked breads showed significant (p < 0.05) differences. At the same time, headspace analysis using a solid-phase microextraction (SPME) method identified 59 volatile compounds. The results of the aroma extracts dilution analysis (AEDA) revealed 19 most odour-active compounds with FD factors in the range of 32–128 as the key odourants of the pineapple breads. Further analysis of the similarities and differences between the pineapple breads in terms of the key odourants were carried out by the application of PLS-DA and PLS-regression coefficients. Results showed that Ppb exhibited strong positive correlations with most of the volatile- and non-volatile compounds, while the Cpb showed significant positive correlations with hexanal and 4-hydroxy-2,5-dimethyl-3(2H)-furanone, and the Fpb had strong positive correlations with lactic acid, benzoic acid, benzaldehyde and ethyl propanoate.
Synthesis of α-hydroxyphosphonates and their antioxidant properties Kalla Reddi Mohan Naidu, Krishnammagari Suresh Kumar, Palanisamy Arulselvan, Chinnappareddy Bhupendra Reddy, Ola Lasekan Archiv Der Pharmazie, 2012 A series of α‐hydroxyphosphonates were synthesized from the reaction of aldehyde (1) with triethylphosphite (2) in the presence of oxone and evaluated for their antioxidant properties against lipid peroxidation, reduced glutathione, superoxide dismutase, and catalase. The majority of the compounds showed promising antioxidant activity. Diethyl anthracen‐9‐yl (hydroxy) methylphosphonate (3n) is the most potent and biologically active compound against free radicals.

Design, synthesis and antiviral potential of 14-aryl/heteroaryl-14H- dibenzo[a, j]xanthenes using an efficient polymer-supported catalyst Kalla Reddi Mohan Naidu, Balam Satheesh Krishna, Mungara Anil Kumar, Palanisamy Arulselvan, Shaik Ibrahim Khalivulla, et al. Molecules, 2012 Polyethyleneglycol bound sulfonic acid (PEG-OSO3H), a chlorosulphonic acid-modified polyethylene glycol was successfully used as an efficient and eco-friendly polymeric catalyst in the synthesis of 14-aryl/heteroaryl-14H-dibenzo[a,j]xanthenes obtained from the reaction of 2-naphthol and carbonyl compounds under solvent-free conditions with short reaction times and excellent yields. The biological properties of these synthesized title compounds revealed that compounds 3b, 3c, 3f and 3i showed highly significant anti-viral activity against tobacco mosaic virus.
Preparation of tetraoxadiphosphadibo-rocane-2,6-diones K. R. Kishore Kumar Reddy, M. Veera Narayana Reddy, K. Reddi Mohan Naidu, G. Chandra Sekhar Reddy, C. Suresh Reddy Synthetic Communications, 2012 Cyclization of aryl/alkyl phosphonic dichlorides (2a–f) with phenylboronic acid/K2CO3/I2 in dry toluene at 60–70 °C afforded 2,6-diaryl/alkyl-4,8-diphenyl-1,3,5,7,2λ 5,6λ 5,4,8-tetraoxadiphosphadiborocane-2,6-diones (3a–f). GRAPHICAL ABSTRACT
Synthesis and antioxidant activity of substituted-1,3,2-diazaphosphole 1-oxides Kalla Reddi Mohan Naidu, Pasupuleti Visweswara Rao, Chamarthi Naga Raju, Kambam Srinivasulu Archiv Der Pharmazie, 2011 Synthesis of 1‐substituted‐1,3,2‐diazaphosphole 1‐oxides (3a–l) were accomplished via a two‐step process. It involves the preparation of diazaphospholo 1‐oxide monochloride intermediate (2) and its subsequent reaction with phenols/amino acid esters in dry THF in the presence of triethylamine at 40–45°C. The structures of newly synthesized compounds were characterized by spectral and elemental analysis. The title compounds were evaluated for their in‐vitro antioxidant properties.
