The title compound, C(18)H(26)O(11), was synthesized by a condensation reaction of 2,3,4,6-tetra-O-acetyl-α-d-galactopyranosyl bromide and butyric acid. The acet-oxy-methyl and butyrate groups are located on the same side of the pyran ring, showing the β configuration for the d-glycosyl ester; the butyl group adopts an extend conformation, the C-C-C-C torsion angle being 179.1 (7)°. In the crystal, the mol-ecules are linked by weak C-H⋯O hydrogen bonds.

Purpose Of Review: The advent of checkpoint immunotherapy has dramatically changed the outcomes for patients with cancer. However, a considerable number of patients have little or no response to therapy. We review recent findings on the connection between the gut microbiota and the immune system, exploring whether this link could enhance the effectiveness of immunotherapy.

Background: Spouses of Alzheimer's disease (AD) patients are at a higher risk of developing incidental dementia. However, the causes and underlying mechanism of this clinical observation remain largely unknown. One possible explanation is linked to microbiota dysbiosis, a condition that has been associated with AD.

December 2024
Edith Cowan University, Perth, Western Australia, Australia.
Background: Our research group is currently exploring the potential of Butyric acid (NaB), a Short Chain Fatty Acid (SCFA), as a novel therapeutic agent for Alzheimer's disease (AD).
Methods: In our investigation using the 5xFAD mouse model of AD, we observed that NaB had significant effects on Aβ levels, as well as on associative learning and cognitive functioning. Notably, we recorded a 40% reduction in brain Aβ and a 25% increase in fear response during both cued and contextual testing.
