In vitro Analysis of the Interaction between Human Serum Albumin and Semi‑Synthetic Clerodanes

Abstract: The interaction between HSA and two semi-synthetic potential anti-cancer agents derived from trans-dehydrocrotonin-methyl-hydrazone (MHDCTN) and phenyl-hydrazone (PHDCTN) was evaluated under physiological conditions at 296, 303 and 310 K by multi-spectroscopic techniques and molecular docking calculations. Steady state fluorescence quenching indicated a ground state association (static quenching) for both samples; however, the quenching induced by PHDCTN was not essentially static and can be accompanied by a d… Show more

“…Understanding and characterizing the interaction of compounds with HSA has attracted much research interest for decades. The nature of these bindings affects pharmacokinetics, pharmacodynamics and therapeutic efficacy and is a key aspect during the process of drug delivery and designing [ 62 ]. The impact of such drugs on the overall conformation, stability and function of HSA is also important.…”

“…A relevância em entendermos as bases estruturais da especificidade da interação entre a proteína HSA e moléculas consideradas como fármacos é devido ao fato de buscarmos e aperfeiçoarmos um melhor entendimento da interação, tanto ao nível atômico como molecular, que poderá definir então as possíveis abordagens terapêuticas para o tratamento de enfermidades e no alívio de sintomas advindos de doenças ou síndromes. [9][10][11][12] A Simulação Computacional utilizada neste trabalho tem como propósito a busca de um maior entendimento das interações entre a proteína HSA e o aminoácido Dansilglicina (DanG), buscando subsídios teóricos para uma possível comparação com os resultados experimentais. Outra característica importante da simulação computacional, adotada neste trabalho, é o seu caráter preditivo das propriedades químicas e físicas de sistemas de interesse como, por exemplo, na predição da conformação adotada pela DanG no sítio de interação da HSA.…”
