Their findings are being featured in the November edition of Experimental Biology and Medicine. SMU Chemistry Professor Edward R. Biehl and UTD Biology Professor Santosh R. D'Mello teamed to test 45 chemical compounds. Four were found to be the most potent protectors of brain cells, or neurons. The synthesized chemicals, called "3-substituted indolin-2-one compounds” are derivatives of another compound called GW5074 which was shown to prevent neurodegeneration in a past report published by the D'Mello lab. While effective at protecting neurons from decay or death, GW5074 is toxic to cells at slightly elevated doses, which makes it unsuitable for clinical testing in patients. The newly identified, second generation compounds maintain the protective feature of GW5074 but are not toxic even at very high doses and hold promise in halting the steady march of neurodegenerative diseases like Alzheimer's and Parkinson's.
