Fluorescent probes for bioimaging of potential biomarkers in Parkinson's disease.

Parkinson's disease (PD), as the second most common neurodegenerative disease, is caused by complex pathological processes and currently remains very difficult to treat. PD brings great distress to patients and imposes a heavy economic burden on society. The number of PD patients is growing as the aging population increases worldwide.

Recent advance on PTP1B inhibitors and their biomedical applications.

Protein Tyrosine Phosphatase 1B (PTP1B), as one of the most important members in PTP superfamily, plays a vital role in conducting various cellular functions. So far, PTP1B has been reported to be involved in the development of many diseases including obesity, diabetes, cancers and cardiovascular diseases. Development of potent and specific PTP1B inhibitors and studies on the structure-activity relationship (SAR) between their chemical structures and their biological activity have drawn increasing attention as they could not only modulate the PTP1B functions inside the cells but also provide useful lead compounds for the treatment of various PTP1B-associated diseases.
