Six microarray assays were analyzed using our method and the distance comparison method. Top ten hits were presented. As the table showed, no molecules were found by the distance comparison method to have a treatment on Alzheimer. In contrast, six of the top ten results detected by our method were negatively related to Dasatinib Alz heimer, promising possible therapeutic functions. Nordi hydroguaiaretic acid could break down pre formed Alzheimers b amyloid fibrils in vitro. Tretinoin was relevant to many pathophysiological fea tures of AD, including amyloid plaques, inflammation, immunological changes, cell death and regeneration pro cesses, altered neurotransmission, and age related changes. It made sense that Nordihydroguaiaretic acid and Tretinoin both had many negative correlation GO modules and could resist AD.

Estradiol and alpha estradiol also prevented AD associated Inhibitors,Modulators,Libraries inflammation with an increasing PPAR gamma expression. Mono rden, also known as radicicol, was a natural product binding to Hsp90 Inhibitors,Modulators,Libraries and altering Inhibitors,Modulators,Libraries its function, while Hsp90 acted as a regulator of patho genic changes that leaded to the neurodegenerative phenotype in AD. LY 294002 held back the traffick ing of APP and APP metabolites by inhibiting phospha tidylinositol 3 kinase. Among the remaining molecules, Prazosin was a non sedating generic medication used for hypertension and benign prostatic Inhibitors,Modulators,Libraries hypertrophy. It antagonizes NE effects at brain postsynaptic alpha 1 adreno receptors and new study said the prazosin improved patients behavioural symptoms such as agitationaggression in AD.

Ful vestrant Inhibitors,Modulators,Libraries was an interesting drug, known to block estro gen receptors. It could also dissociate HSP90 and trigger its intracellular degradation. Considering the positive connection between fulvestrant and Alzheimer, we could infer that estrogen pathway was more impor tant than HSP90 pathway in AD. The last molecule, ikarugamy cin, had no report of any relation with AD, but we thought it might also have a potential side effect to induce AD because of the positive correlated modules in our result. Because almost all molecules were related with AD in the result of our method, we thought that the transgenic AD model was a feasible model of AD in humans. Discussion Since the transgenic animal model of AD was feasible for drug discovery, we further performed an in depth analysis of the results of the AD case, especially for the three can didates fulvestrant, alpha estradiol and monorden.

Alpha estradiol, the predominant sex hormone pre sented in females, and monorden, a kind of HSP90 inhi bitor, were both negatively Ganetespib OSA connected with AD, while fulvestrant, both estrogen blocker and Hsp90 inhibitor, showed positive connection with AD. Researchers had found that the molecular chaperone Hsp90 interacted with unliganded steroid hormone receptors and regulated their activity.
