Galactosylcerebrosides are glycosphingolipids that contain a galactose attached to a ceramide acylated with a hydroxy or non-hydroxy fatty acid. They are metabolic precursors to sulfatides , found primarily in nerve tissues, and are the main glycosphingolipids in the central nervous system. Galactosylcerebrosides are involved in a multitude of cellular processes including cell agglutination, cellular signaling in glycosynapses, cellular development, and activation of T cells. They accumulate in globoid cells in the brain of patients with Krabbe disease, a disorder characterized by a deficiency in galactosylcerebrosidase activity. This product is a mixture of isolated bovine non-hydroxy galactosylcerebrosides.

8-iso Prostaglandin F2β (8-iso PGF2β) is an isomer of PGF2α of non-enzymatic origin. It is one of 64 possible isomers of PGF2α which can be produced by free radical peroxidation of arachidonic acid. 8-iso PGF2β exhibits very weak contraction of human umbilical vein artery and does not promote aggregation of human whole blood. However, 8-iso PGF2β moderately contracts both the canine and porcine pulmonary vein, although the effect is much weaker than that exhibited by other isoprostanes such as 8-iso PGE1, 8-iso PGE2, or 8-iso PGF2α. 8-iso-15-keto PGF2β is a potential metabolite of 8-iso PGF2β via the 15-hydroxy PG dehydrogenase pathway. There are no published reports on the formation or biological activity of 8-iso-15-keto PGF2β.

Globotriaosycleramides are glycosphingolipids found in mammalian cell membranes that are synthesized from lactosylceramides . They act as receptors for Shiga and Shiga-like toxins in vitro and in vivo. Globotriaosylceramides accumulate in endothelial cells, pericytes, vascular smooth muscle cells, renal epithelial cells, dorsal ganglia neuronal cells, and myocardial cells in patients with Fabry disease, a lysosomal storage disorder characterized by a deficiency in the enzyme α-galactosidase A. Globotriaosylceramides act as natural resistance factors to HIV infection, interacting with HIV gp120 to prevent its interaction with chemokine co-receptors and subsequent fusion of HIV to host cell membranes. This product contains a mixture of hydroxy and non-hydroxy fatty acid-containing globotriaosylceramides isolated from porcine red blood cells (RBCs).

(±)8-HEPE is produced by the non-enzymatic oxidation of EPA, containing equal amounts of 8(S)-HEPE and 8(R)-HEPE. The ability of (±)8-HEPE to induce hatching of E. modestus and B. balanoides eggs is probably due to the presence of the 8(R) isomer within the racemic mixture.[1][2]

3-hydroxy Myristic acid methyl ester is a hydroxylated fatty acid methyl ester that has been found in E. camaldulensis and E. torelliana extracts. [1] It is active against M. tuberculosis (MIC = 49.5 μg ml) and is non-cytotoxic to Vero cells (IC50 = >100 μM). 3-hydroxy Myristic acid methyl ester is also a volatile compound that contributes to the aroma of red wild strawberries (F. pentaphylla) but is not present in cultivated strawberries (Fragaria x ananassa).[2] Reference:[1].

N-Methyl-D-aspartate (NMDA) receptors are Ca2+ permeable ligand-gated channels of the central nervous system that are activated after binding of the co-agonists glutamate and glycine. CAY10608 is a propanolamine that potently, selectively, and non-competitively antagonizes the NR2B subunit of NMDA receptors (IC50 = 50 nM). It does not inhibit NR1, NR2A, NR2C, and NR2D subunits and has no significant effects on α-amino-3-hydroxy-5-methyl-4-isoxazolepropioinic acid (AMPA) or kainate receptors. CAY10608 is neuroprotective, since it prevents NMDA-triggered release of lactate dehydrogenase from cultured cortical neurons. Also, CAY10608, when administered intraperitoneally, reduces brain infarct volume resulting from transient ischemia via carotid artery occlusion.

Bupranolol is a non-selective beta blocker without intrinsic sympathomimetic activity (ISA), but with strong membrane stabilizing activity. Its potency is similar to propranolol. Bupranolol is quickly and completely absorbed from the gut. Over 90% undergo first-pass metabolism. Bupranolol has a plasma half life of about two to four hours, with levels never reaching 1 µg l in therapeutic doses. The main metabolite is carboxybupranolol, 4-chloro-3-[3-(1,1-dimethylethylamino)-2-hydroxy-propyloxy]benzoic acid – that is, the methyl group at the benzene ring is oxidized to a carboxyl group –, of which 88% are eliminated renally within 24 hours.
