Preventing Radiation-Induced Injury by Topical Application of an Amifostine Metabolite-Loaded Thermogel.

Purpose: Despite the development of high-precision radiation therapy, ionizing radiation inevitably damages healthy tissues. Radiodermatitis and radioinduced oral mucositis are frequent and significant side effects among patients with breast and head and neck cancer, respectively. These radiation-related injuries negatively affect patient quality of life and can lead to unplanned therapeutic breaks and compromise treatment outcomes.

Naftazone in advanced Parkinson's disease: An acute L-DOPA challenge randomized controlled trial.

Introduction: There is an unmet need to better control motor complications in Parkinson's disease (PD). Naftazone, which exhibits glutamate release inhibition properties, has shown antiparkinsonian and antidyskinetic activity in preclinical models of PD and in a clinical proof of concept study.

Methods: We conducted a double-blind randomized placebo-controlled cross-over trial in PD patients with motor fluctuations and dyskinesia testing naftazone 160 mg/day versus placebo for 14 days.

Synthesis and antitumor characterization of pyrazolic analogues of the marine pyrroloquinoline alkaloids: wakayin and tsitsikammamines.

A series of aza analogues of the marine alkaloids wakayin and tsitsikammamines A and B have been synthesized. The strategy used was based on [3 + 2] cycloaddition reactions involving 3-ethylamine-indole-4,7-dione and different diazo reagents. All the compounds were evaluated in vitro for antiproliferative activity against five distinct cancer cell lines and for their inhibitory effect on topoisomerase isoenzymes I and II.
