Dysregulation of TAF1 function by various mechanisms can lead to disease in the central nervous system, such as the TAF1 Intellectual Disability (ID) Syndrome which currently has no therapeutic treatments. The present invention indicates that a novel T-type calcium channel enhancer, such as SAK3, has disease-modifying effects in animal models of TAF1 editing. In addition, the present invention provides insights into the molecular mechanism by which SAK3 exerts in pharmacologic effects. Moreover, the present findings imply that the T-Type voltage-gated calcium channels are novel molecular targets to develop therapeutics to treat TAF1 ID syndrome and that SAK3 is an attractive drug candidate to treat TAF1 associated neurologic disorders.

Described herein is a multiplexed and high content screening assay using primary neurons for identifying small molecule modulators of neuronal mitochondrial mitostasis (MnMs). Also described is a high throughput screening assay using primary neurons for identifying small molecules that increase mitochondrial function, identified by measuring the electrochemical potential across the inner mitochondrial membrane and ATP generation. Most MnMs that increased mitochondrial content, length and/or health also increased mitochondrial function without altering neurite outgrowth. Some MnMs protect mitochondria in primary neurons from Aβ(1-42) toxicity, glutamate toxicity, increased oxidative stress and the toxic cellular environment associated with Alzheimer's disease. Some MnMs target mitochondria directly. An MnM also increases the synaptic activity of hippocampal neurons and is potent in vivo, increasing the respiration rate of brain mitochondria after administering the compound to mice. The MnMs were demonstrated to protect the mitochondrial population in neurons in an in vivo model of Alzheimer's Disease. Also described is a method for treating a patient suffering from a disorder characterized by dysfunction of neuronal mitostasis, comprising administering to the patient a therapeutically effective amount of a compound (MnM), or a pharmaceutically acceptable salt thereof.
