HEXA inhibitors belong to a distinctive chemical class characterized by their ability to modulate the activity of the human exo-alpha-sialidase enzyme, denoted as HEXA. This enzyme, also known as neuraminidase-1 (NEU1), plays a pivotal role in the catalysis of hydrolysis reactions involving terminal sialic acid residues. Sialic acids are essential components of cell surface glycoconjugates and are involved in various physiological processes, including cell adhesion and signaling. HEXA inhibitors are designed to impede the enzymatic activity of HEXA by binding to its active site, thus disrupting the hydrolysis of sialic acid residues. This inhibition has far-reaching consequences on cellular processes regulated by sialic acids, influencing aspects of cell recognition, adhesion, and communication.HEXA inhibitors exhibit a diverse array of chemical scaffolds, often designed with a focus on interactions with key amino acid residues within the HEXA active site. The development of these inhibitors involves a combination of medicinal chemistry, structural biology, and computational approaches to optimize binding affinity and selectivity. Researchers aim to elucidate the precise molecular mechanisms underlying the interaction between HEXA inhibitors and the enzyme, enabling the design of more potent and specific compounds. The exploration of HEXA inhibitors as a chemical class contributes not only to our understanding of fundamental cellular processes but also holds potential implications for the development of novel strategies in various scientific fields, such as glycobiology and enzymology.
