IDH1 Inhibitor 5 targets MOG cells (IC50: 64.4 nM) and R132H mutant IDH1 gliomas (IC50: 34.9 nM).

Branched fatty acid esters of hydroxy fatty acids (FAHFAs) are lipids that are modulated by dietary changes such as fasting and high-fat diets, and they play a role in insulin sensitivity. These compounds generally consist of a fatty acid chain of either 16 or 18 carbons (for example, palmitoleic, palmitic, oleic, or stearic acid) esterified to a similarly long hydroxy fatty acid. One specific FAHFA, 9-SAHSA, features stearic acid esterified at the 9th carbon of hydroxy stearic acid. The concentration of 9-SAHSA is notably increased in the serum of glucose-tolerant AG4OX mice, which specifically express the Glut4 glucose-transporting protein in adipose tissue.

Pactimibe sulfate is a dual ACAT1/2 inhibitor with anti-atherogenic potential, reducing plasma cholesterol.

5α-Androst-16-en-3-one, a mammalian pheromone present in boar saliva, plays a crucial role in facilitating social and sexual interactions by acting as a volatile chemical cue. It is utilized to prime sows in estrus for mating or artificial insemination, underscoring its significance in reproductive behavior. Additionally, this compound is detected in human sweat and urine, where it is involved in studies concerning receptor-mediated odorant detection and the genetic foundations of anosmias, thereby broadening its scope of relevance beyond the animal kingdom.

TID43, a CK2 inhibitor, exhibits potent inhibition with an IC50 value of 0.3 μM. It is applicable in anti-angiogenic research [1].

Sulforhodamine 101 DHPE, a fluorescent probe, results from the conjugation of sulforhodamine 101, a red fluorescent dye with excitation/emission spectra of 586/605 nm, to the phospholipid 1,2-dipalmitoyl-sn-glycero-3-PE. It effectively integrates into phospholipid bilayers and is utilized for imaging solid supported lipid bilayers, detecting protein-ligand interactions on bilayers, and monitoring lipid probe colocalization in liposomes through resonance energy transfer (RET).

5,6-dehydro Arachidonic acid, an arachidonic acid analog with a 5,6 acetylene, inhibits 5-LO; Ki=15 μM in RBL cells, IC50=10 μM in guinea pig leukocytes.

11β-13,14-Dihydro-15-keto PGF2α, a PGD2 metabolite in the 15-hydroxy PGDH pathway, is formed in human males upon infusion or inhalation of tritiated PGD2, with peak plasma levels of both 11β-PGF2α and 11β-13,14-dihydro-15-keto PGF2α observed within 10 minutes. In human lung homogenates, PGD2 is metabolized firstly to 11β-PGF2α and subsequently to 11β-15-keto-PGF2α in the presence of NAD+, but not to 11β-13,14-dihydro-15-keto PGF2α. Conversely, guinea pig liver and kidney homogenates can metabolize PGD2 to 11β-13,14-dihydro-15-keto PGF2α via 11β-PGF2α, with both NAD+ and NADP+ being requisite for this conversion.

cis-Clopidogrel-MP derivative, also Clopidogrel-MP-AM, is a 3'-methoxyacetophenone Clopidogrel metabolite and oral P2Y12 receptor platelet inhibitor.

9-OxoODE, formed through the oxidation of the allylic hydroxyl group in both 9(S)-HODE and 9(R)-HODE, is present in rabbit reticulocyte plasma and mitochondrial membranes as both 9- and 13-oxoODEs, constituting approximately 2% of the total linoleate residues. The majority of these oxidized linoleate residues are esterified to membrane lipids.

SM-32504 is a potent inhibitor of ACAT.

DC271, a retinoid and RAR agonist, mimics the cellular effects of the endogenous ATRA and the synthetic EC23, by binding to retinoid protein machinery such as CRABPII to facilitate the translocation of ATRA into the nucleus [1].

L791943 is a selective, potent) inhibitor of Phosphodiesterase-4 (PDE4,IC50 of 4.2 nM).

RB 101 suppresses enkephalinase and aminopeptidases; biologically cleaved at disulfide to produce inhibitors of both aminopeptidase N and neutral endopeptidase.

Leukotriene C4 (14,15-LTC4) is an inflammatory mediator synthesized from arachidonic acid through the actions of 15- and 12-lipoxygenases (LOs), involving intermediates such as 15-HpETE and 14,15-LTA4. Unlike the majority of leukotrienes formed via the 5-LO pathway, 14,15-LTC4 is an eoxin predominantly produced by eosinophils, although mast cells and nasal polyps can also synthesize it. While its physiological roles are not well understood, 14,15-LTC4 exhibits limited contractile activity on guinea pig ileum and pulmonary parenchyma. However, it can increase vascular permeability in human endothelial cell monolayers in vitro with potency comparable to 5-LO-derived leukotrienes, contributing to plasma leakage characteristic of inflammation.

KCA-1490 is an inhibitor of dual PDE3/4.

Branched fatty acid esters of hydroxy fatty acids (FAHFAs) are recent discoveries in endogenous lipids that are influenced by dietary changes such as fasting and high-fat diets, showing a link with enhanced insulin sensitivity in mice. These compounds typically feature a C-16 or C-18 fatty acid (e.g., palmitoleic, palmitic, oleic, or stearic acid) bound to a hydroxy group on another C-16 or C-18 fatty chain. A specific FAHFA, 9-POHSA, consists of palmitoleic acid connected at the hydroxy stearic acid's 9th position. This molecule, in particular, exhibits notably increased levels in the serum of glucose-tolerant AG4OX mice, which express the Glut4 glucose transporter predominantly in their adipose tissue. Given the broader family of FAHFAs' roles in enhancing glucose tolerance, promoting insulin secretion, and exerting anti-inflammatory effects, 9-POHSA emerges as a potential bioactive lipid involved in managing metabolic syndrome and inflammation.
