11-cis Retinal is a chromophore that binds to opsin in the mammalian visual system as an inverse agonist forming the inactive conformation of rhodopsin. When 11-cis retinal absorbs a photon of light, it isomerizes to form all-trans retinal beginning the phototransduction cycle, which is the basis for mammalian vision. A G121L mutation in opsin allows 11-cis retinal to bind as a partial agonist and activate rhodopsin in the absence of light. In a moth model of carotenoid deficiency-induced low visual sensitivity, 11-cis retinal application to compound eyes restored visual sensitivity almost completely.

Branched fatty acid esters of hydroxy fatty acids (FAHFAs) are lipids influenced by dietary changes, playing a crucial role in insulin sensitivity. These compounds typically consist of a C-16 or C-18 fatty acid (for example, palmitoleic, palmitic, oleic, or stearic acid) linked to a hydroxy fatty acid with the same carbon chain length. 13-PAHSA, a derivative where palmitic acid is esterified to 13-hydroxy stearic acid, is notably prevalent in the adipose tissue of glucose-tolerant AG4OX mice, which exhibit enhanced glucose transport via the overexpression of the Glut4 glucose transporter. This observation, along with the metabolic benefits seen from other FAHFAs—including improved glucose tolerance, stimulated insulin secretion, and anti-inflammatory properties—suggests that 13-PAHSA may function as a bioactive lipid beneficial in managing metabolic syndrome and inflammation.

Given the established functions of FAHFAs in enhancing glucose tolerance, prompting insulin secretion, and exerting anti-inflammatory properties, 5-SAHSA emerges as a potential bioactive lipid implicated in the management of metabolic syndrome and inflammation.

Pepsin is an endopeptidase that breaks down proteins into smaller peptides and amino acids that can be easily absorbed in the small intestine[1]. Pepsin is stable at pH ranges as high as pH 6. Above this pH, pepsin is rapidly irreversibly inactivated and elevation of pH of the reaction mixture to pH 8 results in complete inactivation of pepsin[2]. Pepsin has been posited to be a reliable biological marker of EER. An immunologic pepsin assay of combined sputum and saliva was determined to be 100% sensitive and 89% specific for detection of EER (based on pH-metry), and an enzymatic test of nasal lavage fluid (100% sensitivity and 92.5% specificity) demonstrated an increased incidence of EER in patients with chronic rhinosinusitis[3]. Cultured hypopharyngeal epithelial (FaDu) cells were exposed to human pepsin (0.1 mg/mL) at pH 7.4 for either 1 hour or 12 hours at 37°C and both mitochondria and Golgi complexes were clearly damaged. This finding reveals a novel mechanism by which pepsin could cause cell damage, potentially even in nonacidic refluxate[4].

A SR33805-induced sensitization of myofilament activation was found to be associated with a slight increase in myosin light chain-2 phosphorylation and a more significant decrease on troponin I (TnI) phosphorylation. Decreased TnI phosphorylation was related to inhibition of protein kinase A activity by SR-33805.

Branched fatty acid esters of hydroxy fatty acids (FAHFAs) are endogenous lipids that are influenced by fasting and high-fat diets and linked to improved insulin sensitivity in mice. These compounds typically feature a chain of either 16 or 18 carbon atoms (for example, palmitoleic, palmitic, oleic, or stearic acid) esterified with a hydroxy fatty acid chain of similar length. One specific FAHFA, known as 5-OAHSA, consists of oleic acid bonded to the fifth carbon of hydroxy stearic acid. Within the FAHFA family, OAHSAs exhibit the highest serum levels in AG4OX mice, which are known for their glucose tolerance attributed to the overexpression of the Glut4 glucose transporter in adipose tissue.

Branched fatty acid esters of hydroxy fatty acids (FAHFAs) have emerged as significant regulators of metabolic processes, influenced by dietary changes such as fasting and high-fat diets, and are linked to improved insulin sensitivity in mice. These compounds typically feature a fatty acid chain, either C-16 or C-18 in length (for example, palmitoleic, palmitic, oleic, or stearic acid), esterified to a hydroxy fatty acid of similar length. A specific FAHFA, 12-POHSA, involves the esterification of palmitoleic acid to the 12th carbon of stearic acid. Notably, 12-POHSA levels are markedly higher in the serum of AG4OX mice, which exhibit enhanced glucose tolerance due to overexpression of the Glut4 glucose transporter in adipose tissue. Given the capacity of FAHFAs to enhance glucose tolerance, stimulate insulin secretion, and exert anti-inflammatory actions, 12-POHSA holds potential as a bioactive lipid implicated in managing metabolic syndrome and inflammation.

13-SAHSA, a branched fatty acid ester of hydroxy fatty acids (FAHFAs), has been found to be involved in metabolic regulation, particularly in relation to fasting, high-fat feeding, and insulin sensitivity.

Notably, 13-SAHSA levels are found to be moderately increased in the serum of AG4OX mice, which are characterized by their glucose tolerance and expression of the Glut4 glucose transporter specifically in their adipose tissue. Similar to other FAHFAs, 13-SAHSA is believed to play a significant role in enhancing glucose tolerance, stimulating insulin secretion, and exerting anti-inflammatory effects, indicating its potential importance in addressing conditions related to metabolic syndrome and inflammation.

Metformin embonate is an AMP-activated protein kinase (AMPK) activator that improves glycemic control by improving insulin sensitivity and decreasing intestinal absorption of glucose.

Branched fatty acid esters of hydroxy fatty acids (FAHFAs) are newly identified endogenous lipids regulated by fasting and high-fat feeding and associated with insulin sensitivity. Structurally, these esters are comprised of a C-16 or C-18 fatty acid (e.g., palmitoleic, palmitic, oleic, or stearic acid) linked to either a C-16 or C-18 hydroxy substituent. 12-PAHSA is a FAHFA in which palmitic acid is esterified at the 12th carbon of hydroxy stearic acid. Among the FAHFA family members, PAHSAs are the most abundant in the adipose tissue of glucose tolerant AG4OX mice, which overexpress the Glut4 glucose transporter specifically in adipose tissue. 12-PAHSA is present at 2- to 3-fold higher levels in adipose tissue of AG4OX mice compared to wild type mice. Levels of 12-PAHSA are also higher in fasted wild-type mice compared to fed mice and are reduced upon high-fat diet-induced obesity in insulin-resistant mice.

Additionally, D18 functions as a cytotoxin for ADC synthesis, specifically for the ADC HE-S2 [1].

RO4927350 is a potent and highly selective non-ATP-competitive MEK1/2 inhibitor. RO4927350 selectively blocks the MAPK pathway signaling both in vitro and in vivo, which results in significant antitumor efficacy in a broad spectrum of tumor models. RO4927350 inhibits not only ERK1/2 but also MEK1/2 phosphorylation. In cancer cells, high basal levels of phospho-MEK1/2 rather than phospho-ERK1/2 seem to correlate with greater sensitivity to RO4927350. Furthermore, RO4927350 prevents a feedback increase in MEK phosphorylation, which has been observed with other MEK inhibitors. RO4927350 represents a novel therapeutic modality in cancers with aberrant MAPK pathway activation.
