C=O group is dad
O atom is mom
Carbonyl is dad and oxygen mom hence c labelled methyl has higher chemical shift  and gets a little more attention
A chemical has Formula: C5H10O2
Rule 2, omit O, gives C5H10
5 – 10/2 + 1 = 1 degree of unsaturation.
Look for 1 pi bond or aliphatic ring.
IR spectrum
The band at 1740 indicates a carbonyl, probably a saturated aliphatic ester. The bands at 3000-2850 indicate C-H alkane stretches. The bands in the region 1320-1000 could be due to C-O stretch, consistent with an ester.

phosphodiesterase type 4 inhibitor, commonly referred to as a PDE4 inhibitor, is a drug used to block the degradative action ofphosphodiesterase 4 (PDE4) on cyclic adenosine monophosphate (cAMP). It is a member of the larger family of PDE inhibitors. The PDE4 family of enzymes are the most prevalent PDE in immune cells. They are predominantly responsible for hydrolyzing cAMP within both immune cells and cells in the central nervous system

PDE4 hydrolyzes cyclic adenosine monophosphate (cAMP) to inactive adenosine monophosphate (AMP). Inhibition of PDE4 blocks hydrolysis of cAMP, thereby increasing levels of cAMP within cells.

Mast Ischemia Drug Gets Orphan Drug Designation

New Drug Approvals

Wed, 11/13/2013
Mast Therapeutics Inc. announced that the U.S. Food and Drug Administration (FDA) has designated MST-188 for the treatment of acute limb ischemia as an orphan drug.

MST-188 (purified poloxamer 188)

MST-188 is a purified form of a nonionic, triblock copolymer (poloxamer 188). It is an investigational agent that binds to hydrophobic surfaces on damaged cells and improves membrane hydration and lowers adhesion and viscosity, particularly under low shear conditions. MST-188 has the potential to reduce ischemic tissue injury and end-organ damage by restoring microvascular function, which is compromised in a wide range of serious and life-threatening diseases and conditions. We initially are developing MST-188 as a treatment for complications arising from sickle cell disease.

How MST-188 Works…


Non-purified forms of poloxamer 188 (P188) have been used in foods, drugs and cosmetics since the 1950s. In the 1980s, extensive research on the mechanisms and potential clinical…

A vitamin (US /ˈvtəmɪn/ or UK /ˈvɪtəmɪn/) is an organic compound required by an organism as a vital nutrient in limited amounts. An organic chemical compound (or related set of compounds) is called a vitamin when it cannot be synthesized in sufficient quantities by an organism, and must be obtained from the diet. Thus, the term is conditional both on the circumstances and on the particular organism. For example, ascorbic acid (vitamin C) is a vitamin for humans, but not for most other animals, and biotin (vitamin H) and vitamin D are required in the human diet only in certain circumstances.
