Sialic Acids as Receptors for Pathogens. [PDF]
Carbohydrates have long been known to mediate intracellular interactions, whether within one organism or between different organisms. Sialic acids (Sias) are carbohydrates that usually occupy the terminal positions in longer carbohydrate chains, which ...

Unraveling the impact of sialic acids on the immune landscape and immunotherapy efficacy in pancreatic cancer. [PDF]
Background Pancreatic ductal adenocarcinoma (PDAC) is one of the deadliest cancers. Despite the successful application of immune checkpoint blockade in a range of human cancers, immunotherapy in PDAC remains unsuccessful.

Sialic acid 9-phosphate synthetase, an enzyme that condenses phosphoenolpyruvate with N-acyl- d -mannosamine 6-phosphate to yield sialic acid 9-phosphate and inorganic phosphate, was purified approximately 800-fold from extracts of hog submaxillary gland. The enzyme was specific for the indicated substrates, and the available data suggest that a single

Intramolecular Lactones of Sialic Acids. [PDF]
The so-called “sialo-chemical-biology” has become an attractive research area, as an increasing number of natural products containing a sialic acid moiety have been shown to play important roles in biological, pathological, and immunological processes.

Identification of Potential Binding Sites of Sialic Acids on the RBD Domain of SARS-CoV-2 Spike Protein. [PDF]
COVID-19, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is still an emergent pandemic for humans. The virus infection is achieved by penetrating its spike protein to host cells via binding with ACE2.
