Aliphatic chain compounds include aliphatic compounds and chain compounds containing other elements or groups. Aliphatic hydrocarbons are hydrocarbons with the basic properties of aliphatic compounds. In aliphatic compounds, carbon atoms are arranged in straight chain, branched chain or cyclic, which are respectively called straight chain aliphatic hydrocarbons, branched chain aliphatic hydrocarbons and alicyclic hydrocarbons. Some cyclic hydrocarbons are different in nature from aromatic hydrocarbons, and are very similar to aliphatic hydrocarbons. Such cyclic hydrocarbons are called alicyclic hydrocarbons. In this way, aliphatic hydrocarbons become a general term for all hydrocarbons except aromatic hydrocarbons. Aliphatic hydrocarbons and their derivatives (including halogenated hydrocarbons) and alicyclic hydrocarbons and their derivatives are collectively referred to as aliphatic compounds.
The Journal of Medicinal Chemistry recently publishes an article titled, “Discovery of Clinical Candidate PF-06648671: A Potent γ-Secretase Modulator for the Treatment of Alzheimer’s Disease”. Amyloid β-peptide (Aβ) accumulation is one of the key hallmarks of Alzheimer’s disease (AD). γ-secretase cleaves the amyloid precursor protein (APP) into pathologically relevant Aβs, and has been widely studied as a potential target for the treatment of AD.
Pfizer‘s PF-06648671 is a Gamma secretase modulator (GSM) targeting APP processing. It is found to have excellent central exposure in human and robust reduction of amyloidogenic forms (Aβ42) in cerebrospinal fluid (CSF).
