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.
In organic chemistry, a carbonyl group is a functional group with the formula C=O, composed of a carbon atom double-bonded to an oxygen atom, and it is divalent at the C atom. It is common to several classes of organic compounds (such as aldehydes, ketones and carboxylic acids), as part of many larger functional groups. A compound containing a carbonyl group is often referred to as a carbonyl compound.
The Journal of Medicinal Chemistry recently publishes an article titled, “Discovery of Nelutroctiv (CK-136), a Selective Cardiac Troponin Activator for the Treatment of Cardiovascular Diseases Associated with Reduced Cardiac Contractility”. Heart failure (HF) is a lifelong clinical syndrome and remains a major societal concern. Cardiac myosin activators constitute a new class of inotropes and are found to be a viable therapeutic approach for increasing myocardial contractility.
CK-136 is a small molecule cardiac troponin activator that is discovered under a previous joint research program between Cytokinetics and Amgen. It acts on the sarcomere and is designed to improve myocardial contractility by sensitizing cardiac troponin to calcium, increasing actin-myosin cross bridge formation during each cardiac cycle. CK-136 is developed as a potential treatment for heart failure (HF) with reduced ejection fraction (HFrEF) and other types of heart failure, and currently under phase 1 clinical investigation.
