TL;DR: The dramatic elevation in endogenous levels of NATs following acute or chronic inactivation of FAAH, in conjunction with the pharmacological effects of these lipids on TRP channels, suggests the existence of a second major lipid signaling system regulated by FAAH in vivo.
Abstract: Fatty acid amide hydrolase (FAAH) is an integral membrane enzyme that catabolizes several bioactive lipids in vivo. Most of the physiological substrates of FAAH characterized to date belong to the N-acyl ethanolamine (NAE) class of fatty acid amides, including the endocannabinoid anandamide, the anti-inflammatory lipid N-palmitoyl ethanolamine, and the satiating factor N-oleoyl ethanolamine. We recently identified a second structural class of fatty acid amides regulated by FAAH in vivo: the N-acyl taurines (NATs). Global metabolite profiling revealed high concentrations of long chain (≥C20) saturated NATs in the central nervous system (CNS) of FAAH(−/−) mice. Here, we use metabolite profiling to characterize the FAAH−NAT system in peripheral mouse tissues. Livers and kidneys of FAAH(−/−) mice possessed dramatic elevations in NATs, which, in contrast to those detected in the CNS, were enriched in polyunsaturated acyl chains (e.g., C20:4, C22:6). Peripheral NATs rose more than 10-fold within 1 h following ...

TL;DR: Simulations using molecular dynamics showed that three amino acid moieties have the same spatial orientation as the corresponding pharmacophoric groups of the opioid peptide PLO17, demonstrating that this peptide may cross the blood-brain barrier.
Abstract: A synthetic combinatorial library containing 52,128,400 D-amino acid hexapeptides was used to identify a ligand for the mu opioid receptor. The peptide, Ac-rfwink-NH2, bears no resemblance to any known opioid peptide. Simulations using molecular dynamics, however, showed that three amino acid moieties have the same spatial orientation as the corresponding pharmacophoric groups of the opioid peptide PLO17. Ac-rfwink-NH2 was shown to be a potent agonist at the mu receptor and induced long-lasting analgesia in mice. Analgesia produced by intraperitoneally administered Ac-rfwink-NH2 was blocked by intracerebroventricular administration of naloxone, demonstrating that this peptide may cross the blood-brain barrier.

TL;DR: Reversed phase-high performance chromatography (RP-HPLC) and surface plasmon resonance (SPR) are emerging techniques for the study of the dynamics of the interactions between cytolytic and antimicrobial peptides and lipid surfaces and immobilization of lipid moieties onto RP- HPLC sorbent allows the investigation of peptide conformational transition upon interaction with membrane surfaces.

TL;DR: A non-nucleotide, small-molecule STING agonist, termed SR-717, that demonstrates broad interspecies and interallelic specificity and functions as a direct cyclic guanosine monophosphate–adenosine monophile mimetic that induces the same “closed” conformation of STING.
Abstract: Stimulator of interferon genes (STING) links innate immunity to biological processes ranging from antitumor immunity to microbiome homeostasis. Mechanistic understanding of the anticancer potential for STING receptor activation is currently limited by metabolic instability of the natural cyclic dinucleotide (CDN) ligands. From a pathway-targeted cell-based screen, we identified a non-nucleotide, small-molecule STING agonist, termed SR-717, that demonstrates broad interspecies and interallelic specificity. A 1.8-angstrom cocrystal structure revealed that SR-717 functions as a direct cyclic guanosine monophosphate-adenosine monophosphate (cGAMP) mimetic that induces the same "closed" conformation of STING. SR-717 displayed antitumor activity; promoted the activation of CD8+ T, natural killer, and dendritic cells in relevant tissues; and facilitated antigen cross-priming. SR-717 also induced the expression of clinically relevant targets, including programmed cell death 1 ligand 1 (PD-L1), in a STING-dependent manner.
