Synthesis and structure of 1,3-dimethyl-5-( p -sulfonamide-phenylazo)-6-aminouracil and its Ni(II) complex: Topological insights and investigation for noncovalent interactions

Quantum Chemical Study on the Structure and Energetics of Binary Ionic Porphyrin Complexes

“…It is well known that the electrostatic forces between the porphyrin layers are highly responsible for the structural stability and tubular formation of porphyrin nanoaggregates . Hence it is worthwhile looking into the electrostatic potentials, as it is a useful tool for understanding the chemical and physical properties of various nonbonded structures and even supramolecular aggregates . Hence in this study, molecular electrostatic potentials mapped over the electron isodensity surface are obtained for the isolated structures of [H 4 TPPS 4 ] 2− , [X'SnXTP], and [X'SnXTPH] 4+ and their respective complexes [H 4 TPPS 4 ] 2− ∙∙∙[X'SnXTP] and [H 4 TPPS 4 ] 2− ∙∙∙[X'SnXTPH] 4+ at the HF/STO‐3G level of theory (see Figures and ).…”

Facile Synthesis of 5-Bromo-N-Alkylthiophene-2-Sulfonamides and Its Activities Against Clinically Isolated New Delhi Metallo-β-Lactamase Producing Klebsiella pneumoniae ST147

“… 24 Additionally, sulfonamide derivatives are frequently utilized as anti-bacterial and antiviral drugs in chemotherapy. 25–27 Due to their structural similarities, these medications work as competitive antagonists of 4-aminobenzoic acid. Sulfonamides have anti-bacterial properties and work by incorporating 4-amino benzoic acid into the folic acid pathway, inhibiting folate synthase.…”

Antimicrobial sulphonamide azo dyes

“…The biological activities responsible for antimicrobial activity have been reported . Chemotherapeutic sulphonamide derivatives are widely used as anti‐bacterial and anti‐viral agents, where the mechanism of action of sulphonamide involves the incorporation of 4‐amino benzoic acid in the folic acid pathway to inhibit foliate synthase. In this respect, sulphonamide hinders folic acid synthesis in bacteria, which consequently limits the production of purines .…”
