Publication number: 20170152261Abstract: The invention provides a series of bioactive small molecules that target expanded r(CGG) repeats, termed r(CGG)exp, that causes Fragile X-associated Tremor Ataxia Syndrome (FXTAS). The compound was identified by using information on the chemotypes and RNA motifs that interact. Specifically. 9-hydroxy-5,11-dimethyl-2-(2-(piperidin-1-yl)ethyl)-6H-pyrido[4,3-b]carbazol-2-ium, binds the 5?CGG/3?GGC motifs in r(CGG)exp and disrupts a toxic r(CGG)exp-protein complex. Specifically, dimeric compounds incorporating two 9-hydroxyellipticine analog structures can even more potently bind the 5?CGG/3?GGC motifs in r(CGG)exp and disrupts a toxic r(CGG)exp-protein complex. Structure-activity relationships (SAR) studies determined that the alkylated pyridyl and phenolic side chains are important chemotypes that drive molecular recognition of r(CGG) repeats, such as r(CGG)exp.Type: ApplicationFiled: January 23, 2017Publication date: June 1, 2017Inventors: Matthew D.

Patent number: 7963153Abstract: A method, a system and a computer readable medium for dynamic mode AFM amplitude versus distance curve acquisition. In an embodiment, a constant force feedback mechanism is enabled prior to the first time an AFM probe tip contacts a sample. The feedback mechanism setpoint is iteratively reduced while at least phase and amplitude of the probe tip are recorded as a function of the relative z-height of a cantilever coupled to the probe tip. The feedback mechanism setpoint may be repeatedly swept between upper and lower bounds to average out drift between the cantilever and sample. Upon detecting a threshold, an absolute tip-to-sample distance is determined and correlated to the relative z-heights. The amplitude and phase data recorded prior to tip-sample contact is then determined as a function of absolute tip-to-sample distance.Type: GrantFiled: December 12, 2007Date of Patent: June 21, 2011Assignee: Applied Materials, Inc.Inventors: Chikuang Charles Wang, Biao Liu, Yuri S.
