Effect of methotrexate and its photodegradation products on the temperature induced denaturation of human serum albumin


Authors: Preisz, Zsolt; Kunsagi-Mate, Sandor

Effect of the photodegradation of chemotherapeutic agent methotrexate on the denaturation of human serum albumin has been studied by differential scanning calorimetry and fluorimetric measurements. Photoluminescence studies highlighted entropy driven binding of both methotrexate molecules and its degradation products to the albumin molecules. The calorimetric measurements evaluated by the Kissinger method show elevated activation energy in the presence of methotrexate. Similar but moderated enhancement of the activation energy was obtained in the presence of the photodegradation products of methotrexate. These results highlight stabilization of the human serum albumin by the methotrexate drug which finding may contribute to fine tuning of methotrexate applications in therapy. (C) 2020 The Authors.

Flexible and disposable gold nanoparticles-N-doped carbon-modified electrochemical sensor for simultaneous detection of dopamine and uric acid


Authors: Patil, Aniruddha B.; Zheng, Chuanbao; Ma, Liyun; Wu, Ronghui; Mengane, Sharwari K.; Zhang, Yifan; Liu, Xiaotian; Meng, Zhaohui; Zhang, Wenli; Xu, Zijie; Chen, Caifeng; Huang, Jiani; Liu, Xiang Yang

Catalytic and electrocatalytic applications of supported metal nanoparticles are hindered due to an aggregation of metal nanoparticles and catalytic leaching under harsh operations. Hence, stable and leaching free catalysts with high surface area are extremely desirable but also challenging. Here we report a gold nanoparticles-hosted mesoporous nitrogen doped carbon matrix, which is prepared using bovine serum albumin (BSA) through calcination. BSA plays three roles in this process as a reducing agent, capping agent and carbon precursor, hence the protocol exhibits economic and sustainable. Gold nanoparticles at N-doped BSA carbon (AuNPs@NBSAC)-modified three-electrode strip-based flexible sensor system has been developed, which displayed effective, sensitive and selective for simultaneous detection of uric acid (UA) and dopamine (DA). The AuNPs@NBSAC-modified sensor showed an excellent response toward DA with a linear response throughout the concentration range from 1 to 50 mu M and a detection limit of 0.05 mu M. It also exhibited an excellent response toward UA, with a wide detection range from 5 to 200 mu M as well as a detection limit of 0.1 mu M. The findings suggest that the AuNPs@NBSAC nanohybrid reveals promising applications and can be considered as potential electrode materials for development of electrochemical biosensors.
