Microfluidic-Chip-Based Formulation and In Vivo Evaluations of Squalene Oil Emulsion Adjuvants for Subunit Vaccines.

Background: Adjuvants play a crucial role in improving the immunogenicity of various antigens in vaccines. Squalene-in-water emulsions are clinically established vaccine adjuvants that improve immune responses, particularly during a pandemic. Current manufacturing processes for these emulsion adjuvants include microfluidizers and homogenizers and these processes have been used to produce emulsion adjuvants to meet global demands during a pandemic.

In vivo evolution of env in SHIV-AD8-infected rhesus macaques after AAV-vectored delivery of eCD4-Ig.

eCD4-immunoglobulin (Ig) is an HIV entry inhibitor that mimics the engagement of both CD4 and CCR5 with the HIV envelope (Env) protein, a property that imbues it with remarkable potency and breadth. However, env is exceptionally genetically malleable and can evolve to escape a wide variety of entry inhibitors. Here we document the evolution of partial eCD4-Ig resistance in SHIV-AD8-infected rhesus macaques (RMs) treated with adeno-associated virus vectors encoding eCD4-Ig.

Synthesis of Janus All- Tetrafluorocyclohexanes Carrying 1,4-Diether Motifs.

Nucleophilic aromatic substitutions (SAr) of alkoxides on pentafluoroaryl ethers are explored as a first step in a synthesis sequence to generate all- 2,3,5,6-tetrafluorocyclohexyl-1,4-dialkyl ethers . The SAr reaction was explored both experimentally and theoretically to rationalize // selectivities. -Butyl deprotection of products followed by phenol alkylations introduces versatility to the synthesis.

Conformational Analysis Explores the Role of Electrostatic Nonclassical CF···HC Hydrogen Bonding Interactions in Selectively Halogenated Cyclohexanes.

The conformational equilibria of selectively halogenated cyclohexanes are explored both experimentally (VT-NMR) for 1,1,4,-trifluorocyclohexane and by computational analysis (M06-2X/aug-cc-pVTZ level), with the latter approach extending to a wider range of more highly fluorinated cyclohexanes. Perhaps unexpectedly, is preferred over the conformation by Δ = 1.06 kcal mol, contradicting the accepted norm for substituents on cyclohexanes.
