Phosphatidylserine is a naturally occurring phospholipid that comprises 2-10% of total phospholipids in mammals and is enriched in the central nervous system, particularly the retina. It is anionic and found mainly on the inner leaflet of the cell membrane. It is biosynthesized from phosphatidylcholine or phosphatidylethanolamine by phosphatidyl synthase 1 (PSS1) or PSS2, respectively, in the endoplasmic reticulum and can be reversibly converted back by the same enzymes. It can also be irreversibly converted to phosphatidylethanolamine by phosphatidylserine decarboxylase in the mitochondria. Phosphatidylserine binds to T cell immunoglobulin mucin type 1 (TIM-1) and TIM-4 receptors as well as brain-specific angiogenesis inhibitor 1 (BAI1), leading to anti-inflammatory and anti-atherosclerotic effects. It is also a cofactor involved in the activation of various signaling pathways through activation of protein kinase C, neutral sphingomyelinase, and c-Raf-1 protein kinase among others. Phosphatidylserine is externalized during apoptosis by scramblases in the plasma membrane as a signal for phagocytes to engulf the cell. Phosphatidylserines (bovine) is a mixture of bovine phosphatidylserines containing fatty acids with variable chain lengths at the sn-1 and sn-2 positions.

Ambroxol-d5 is intended for use as an internal standard for the quantification of ambroxol by GC- or LC-MS. Ambroxol is an expectorant and active metabolite of bromhexine. It decreases short-circuit currents in electrically stimulated isolated canine tracheal epithelial cells when applied submucosally. Ambroxol decreases IL-13-induced production of mucin 5AC (MUC5AC) in primary human airway epithelial cells and inhibits IL-13-induced decreases in the mucociliary transport rate of endogenous particles in the same cells. Ambroxol increases phenol red secretion, a marker of expectorant activity, in mice when administered at doses of 30, 60, or 120 mg kg. Formulations containing ambroxol have been used in the treatment of acute or chronic respiratory conditions.

Guaifenesin-d3 is intended for use as an internal standard for the quantification of guaifenesin by GC- or LC-MS. Guaifenesin is an expectorant. It inhibits production of mucin 5AC (MUC5AC), reduces mucus viscosity and elasticity, and increases the mucociliary transport rate of endogenous particles in primary human tracheobronchial epithelial cells in a concentration-dependent manner. Guaifenesin increases phenol red secretion, a marker of expectorant activity, in rats.3 Formulations containing guaifenesin have been used as expectorants in the treatment of the common cold and chronic bronchitis.
