Projects

Research Interest

  • Theranostic prodrugs: The advances in genomics, proteomics, and bioinformatics have directed to develop new type of healthcare system to reduce the drug abuse, safety and precise treatment. In search of innovative product for health care, the term, “theranostic” gained interest in clinical science. It is an appealing formulation in combination of diagnosis and therapy to improve the biodistribution and systematic administration of therapeutic in the target place. Importantly, it could be provided clear-cut solution for long time pending diseases, namely, genetic diseases and oncogenic diseases. Present needs motivated us to develop “theranostic” as future of personalized healthcare.  
  • Molecular Sensor (Chemo-sensors & bio-sensors): To understand the chemical transformation at the molecular level in the cellular milieus is challenging and it motivates the chemist to search new way to learn the biological system. Thus bio-inspired emerging strategy for fluorescent based bio-imaging is to sort and identify the species of interest within this complex microenvironment by exploiting differences in molecular reactivity.
  • MRI Contrast Agent: Magnetic resonance imaging is widely used as clinical imaging tools which provide noninvasive three dimensional spatial images of hard and soft tissues as well. Clinically, one third cases gadolinium based contrast agents are used to enhance image contrast. Presently contrast agents are incapable to provide brighter images under higher magnetic field scanner as because of high tumbling motion, mono hydration number of gadolinium complex. Additionally, the conventional MRI contrast agents are incapable to give meaningful information on various metabolic irregularities which are being associated with various diseases etc. Thus, challenge has been focused to develop gadolinium/manganese based T1 MR Contrast agent which can provide information / interrogate on metabolic process.

S., Kothurkar, Nd, Mishra, N., and Bhuniya, S., “GSH-responsive biotinylated poly(vinyl alcohol)-grafted GO as a nanocarrier for targeted delivery of camptothecin”, RSC Advances, vol. 6, pp. 62385-62389, 2016.[Abstract]

A water-soluble and biocompatible polymer, i.e. biotinylated poly(vinyl alcohol)-grafted graphene oxide (GO), was used as a nanocarrier for targeted delivery of anticancer drug camptothecin (CPT). The extent of CPT release in the presence of glutathione (GSH) from GO-biotinPVA-CPT was monitored by the increase in the fluorescence intensity, at λmax = 450 nm. The cell-specific (HeLa) antiproliferative activity of GO-biotinPVA-CPT makes it suitable to be used for targeted delivery of chemotherapeutics to cancerous cells. More »»

The advances in genomics, proteomics, and bioinformatics have directed the development of new anticancer agents to reduce drug abuse and increase safe and specific drug treatment. Theranostics, combining therapy and diagnosis, is an appealing approach for chemotherapy in medicine which exhibits improved biodistribution, selective cancer targeting ability, reduced toxicity, masked drug efficacy, and minimum side effects. The role of diagnosis tools in theranostics is to collect the information of the diseased state before and after specific treatment. Magnetic particle-, mesoporous silica-, various carbon allotrope-, and polymer nanoparticle-based theranostic systems are well accepted and clinically significant. Currently, small conjugate-based systems have received much attention for cancer treatment and diagnosis. The structural architecture of these systems is relatively simple, compact, biocompatible, and unidirectional. In this tutorial review, we summarize the latest developments on small conjugate based theranostic agents for tumor treatment and diagnosis using fluorescence and magnetic resonance imaging (MRI). © The Royal Society of Chemistry 2015.

A cellular responsive, highly selective fluorogenic and chromogenic chemodosimeter probe for HNO is developed. This new probe showed ∼30 fold fluorescence enhancement in the presence of HNO and is sensitive to HNO at concentrations as low as 0.02 μM. Further, it is capable of detecting HNO levels in cellular milieus as well as in live specimens e.g. C. elegans.

2014 Journal Article S. Bhuniya, Maiti, S., Kim, E. - J., Lee, H., Sessler, J. L., Hong, K. Soo, and Kim, J. Seung, “An activatable theranostic for targeted cancer therapy and imaging”, Angewandte Chemie International Edition, vol. 53, pp. 4469–4474, 2014.[Abstract]

A new theranostic strategy is described. It is based on the use of an “all in one” prodrug, namely the biotinylated piperazine-rhodol conjugate 4 a. This conjugate, which incorporates the anticancer drug SN-38, undergoes self-immolative cleavage when exposed to biological thiols. This leads to the tumor-targeted release of the active SN-38 payload along with fluorophore 1 a. This release is made selective as the result of the biotin functionality. Fluorophore 1 a is 32-fold more fluorescent than prodrug 4 a. It permits the delivery and release of the SN-38 payload to be monitored easily in vitro and in vivo, as inferred from cell studies and ex vivo analyses of mice xenografts derived from HeLa cells, respectively. Prodrug 4 a also displays anticancer activity in the HeLa cell murine xenograft tumor model. On the basis of these findings we suggest that the present strategy, which combines within a single agent the key functions of targeting, release, imaging, and treatment, may have a role to play in cancer diagnosis and therapy.

A naphthalimide-based highly selective colorimetric and ratiometric fluorescent probe for the fluoride ion displayed both one- and two-photon ratiometric changes. Upon reaction with the F− (TBA+ and Na+ salts) anion in CH3CN as well as in aqueous buffer solution, probe 1 shows dramatic color changes from colorless to jade-green and remarkable ratiometric fluorescence enhancements signals. These properties are mechanistically ascribed to a fluoride-triggered Si−O bond cleavage that resulted in a green fluorescent 4-amino-1,8-naphthalimide.

A new probe system for fluorogenic sensing of mercury ions has been designed and synthesized. It is the first intermolecular reaction-based fluorogenic chemodosimetric probe system for Hg(II) ion recognition. High and low concentrations of mercury ions gave different fluorescence responses that could easily be distinguished by the naked eye. This unique system allows detection of the concentration and presence of the mercury ion.

2010 Journal Article H. Sung Jung, Ko, K. Chul, Lee, J. Hong, Kim, S. Hoon, Bhuniya, S., Lee, J. Yong, Kim, Y., Kim, S. Jin, and Kim, J. Seung, “Rationally Designed Fluorescence Turn-On Sensors: A New Design Strategy Based on Orbital Control”, Inorganic Chemistry, vol. 49, pp. 8552-8557, 2010.[Abstract]

Herein, we explore a new strategy in the chemo-sensor field for fluorescence amplification upon binding with metal ions based on controlled participation of the nitrogen lone pair orbital. The basic architecture of the sensor entails a fluorophore, the sp2 hybridized nitrogen lone pair (-C═N-), and a chelator site referred to as the control part. Though nonplanar and nonfluorescent, compound IC1 achieved pseudo planarity from binding with Zn2+ as indicated by the increased fluorescence signal. Its other analogue (IC2) is also planar, and unlike IC1-Zn2+ was fluorescent with a lack of binding affinity to metal ions. The time-dependent density functional theory (TDDFT) calculations revealed that the fluorescence amplification was due to the blocking of the nitrogen lone pair orbital; unlikely geometrical rearrangements were insignificant. This could indicate a breakthrough concept in the future design of fluorescent turn-on sensors.

Epoxy resins are among the most versatile engineering structural materials. A wide variety of epoxy resins are commercially available, but most are brittle. Several approaches have been used to improve the toughness of epoxy resins, including the addition of fillers, rubber particles, thermoplastics, and their hybrids, as well as interpenetrating polymer networks (IPNs) of acrylic, polyurethane, and flexibilizers such as polyols. This last approach has not received much attention; none of them have been able to suitably increase resin toughness with out sacrificing tensile properties. Therefore, in an attempt to fill this gap, we experimented with newly synthesized hydroxy-terminated silicon-modified polyurethane (SiMPU) oligomers as toughening agents for epoxy resins. SiMPU oligomers were synthesized from dimethyl dichlorosilane, poly(ethylene glycol) (weight-average molecular weight ∼ 200), and toluene 2,4-diisocyanate and characterized with IR, 1H-NMR and 13C-NMR, and gel permeation chromatography. The synthesized SiMPU oligomers, with different concentrations, formed IPNs within the epoxy resins (diglycidyl ether of bisphenol A). The resultant IPN products were cured with diaminodiphenyl sulfone, diaminodiphenyl ether, and a Ciba–Geigy hardener under various curing conditions. Various mechanical properties, including the lap-shear, peel, and impact strength, were evaluated. The results showed that 15 phr SiMPU led to better impact strength of epoxy resins than the others without the deterioration of the tensile properties. The impact strength increased continuously and reached a maximum value (five times greater than that of the virgin resin) at a critical modifier concentration (20 phr). The critical stress intensity factor reached 3.0 MPa m1/2 (it was only 0.95 MPa m1/2 for the virgin resin). © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 90: 1497–1506, 2003 More »»

The curing behavior of phosphorus based epoxy terminated polymers was studied using diaminodiphenyl ether, diaminodiphenyl sulfone, benzophenone tetracarboxylic dianhydride and the commercial hardener of Ciba-Geigy's two-pack araldite, as curing agent. The adhesive strength of these adhesives was measured by various \{ASTM\} methods like lap-shear, peel, and cohesive tests on metal–metal, wood–wood and wood–metal interfaces. All these results were compared with the synthesized epoxy resins prepared from bisphenol-A and epichlorohydrin having the epoxy equivalent value of 0.519. The thermal stability of both the virgin resin and its cured form was also studied by thermogravimetric analysis. More »»
