WebMentioning: 27 - Small molecule covalent kinase inhibitors (CKIs) have entered a new era in drug discovery, which have the advantage for sustained target inhibition and high selectivity. An increased understanding of binding kinetics of CKIs and discovery of additional irreversible and reversible-covalent cysteine-targeted warheads has inspired the … WebFormation of Covalent Bonds. Nonmetal atoms frequently form covalent bonds with other nonmetal atoms. For example, the hydrogen molecule, H 2, contains a covalent bond between its two hydrogen atoms. Figure 1 illustrates why this bond is formed. Starting on the far right, we have two separate hydrogen atoms with a particular potential energy, …
