Protonation of Planar and Nonplanar Porphyrins: A Calorimetric and Computational Study The Journal of Physical Chemistry Part A (2020)
Herein, we report the first calorimetric study of the protonation of planar and nonplanar free-base porphyrins: H2OETPP (strongly saddled by its substituents), H2T(tBu)P (strongly ruffled by its substituents), and the nominally planar porphyrins (npPs) H2OEP, ...
Stay calm and focus on the learning outcomes: Tools for taking biophysical chemistry online Biochemistry and Molecular Biology Education (2020)
Course specific learning outcomes are an important tool to define the scope of a course and can be very helpful when designing experiments and assessments. With slight modification, these learning outcomes can serve as a ...
The E-STEAM (Exploring Science, Technology, Engineering, Arts and Math) Project for Girls Mentoring Program The Chronicle of Mentoring and Coaching (2018)
The Nova Southeastern University Branch of the American Association of University Women (NSU AAUW) developed the E-STEAM Project for Girls - an initiative to attract at risk 12-17-year-old girls to STEAM careers (Science, Technology, Engineering, ...
Qualitative Analysis of Sequence Specific Binding of Flavones to DNA Using Restriction Endonuclease Activity Assays Biopolymers (2013)
Flavones, found in nature as secondary plant metabolites, have shown efficacy as anti-cancer agents. We have examined the binding of two flavones, 5,7-dihydroxy-3,6,8-trimethoxy-2-phenyl-4H-chromen-4-one (5,7-dihydroxy-3,6,8-trimethoxy flavone; FlavA) and 3,5-dihydroxy-6,7,8-trimethoxy-2-phenyl-4H-chromen-4-one (3,5-dihydroxy-6,7,8-trimethoxy flavone; FlavB), to phiX174 RF DNA ...
Anti-Neoplastic Activity of Two Flavone Isomers Derived from Gnaphalium elegans and Achyrocline bogotensis PLoS One (2012)
Over 4000 flavonoids have been identified so far and among these, many are known to have antitumor activities. The basis of the relationships between chemical structures, type and position of substituent groups and the effects ...

Photoactivation Investigation of the Mesotetra(N-methyl-2-pyridyl) and Meso-tetra(Nmethyl- 3-pyridyl) Porphyrins Under Different Light Intensities Chemistry and Physics Faculty Proceedings, Presentations, Speeches, Lectures (2019)
A fluorescence lamp with wavelengths between 530-650 nm was used to activate two different isomers of substituted porphyrins (meso-tetra(N-methyl-2-pyridyl) and meso-tetra(N-methyl-3-pyridyl)). Each isomer was exposed to three different intensities (2.0, 4.5, and 8.0 W/m2) for ...
Photo Activation Study of Three Isomers of N-pyridyl Mesosubstituted Porphyrin Chemistry and Physics Faculty Proceedings, Presentations, Speeches, Lectures (2019)
Light of particular wavelengths can activate some types of porphyrins more easily than others. In this project, we will use a fluorescence light to activate three different isomers of N-pyridyl mesosubstituted porphyrin using different intensities. ...
Cationic Porphyrin Basicity and Possible Implications in Photodynamic Therapy Chemistry and Physics Faculty Proceedings, Presentations, Speeches, Lectures (2018)
Photodynamic therapy (PDT) is a cutting edge cancer treatment that is currently being researched with great interest. PDT uses an agent, commonly a porphyrin molecule, thatis activated when it is exposed to specific wavelenghths of ...
Sequence and topological specificity in the binding of tetra(N-methylpyridyl)porphines to DNAs Chemistry and Physics Faculty Proceedings, Presentations, Speeches, Lectures (2015)
Pyridyl porphyrins have gained attention as potential antitumor agents. In this study we report on the binding of family of tetra(methylpyridyl)porphines to relaxed and supercoiled circular phiX197RF DNA. Binding to this DNAs was probed using ...
