(S)-Npx has been used as a chiral selector for chromatographic separation of a variety of racemates, using both direct and indirect methods
The method is based on the difference between the interactions of naproxen (Nap) enantiomers with a chiral modified electrode surface
Method development
A novel voltammetric chiral sensor (GCE/rGO-TsPro-Cs) for Nap enantiomers was designed
Naproxen was found to follow somewhat different patterns of
It is a drug for the treatment of arthritis ,and it is a chiral drug
029 Abstract A simple, fast and green method for chiral recognition of S- and R-naproxen has been introduced
Chiral bipolar hosts of (R/S)-L-2mCPCN are synthesized, which shows high singlet/triplet energy levels and clear circularly polarized luminescence

Saharanpur (42 km) Naproxen contains one chiral center bound to the 6-position of the naphthyl ring; see Figure 1
The two non-superimposable mirror-image forms of chiral molecules are called enantiomers
The most commonly encountered stereogenic unit, [2] that confers chirality to drug molecules are stereogenic center
The different enantiomers of a chiral molecule are expected to exhibit identical electronic, vibrational, and rotational spectra to very high degrees of resolution
Carbon #2 is bonded to two identical substituents (methyl groups), not 4 different groups, and so it is not a chiral center
In order to investigate the stereochemistry of reactions at the phosphate center, 17 O and 18 O isotopes of oxygen (the ‘normal’ isotope is 16 O) can be incorporated to create chiral phosphate groups
Chirality of pharmaceutical substances is an important aspect in drug research because it determines how enantiomers will interact with chiral biological targets

Naproxen (Npx), also known as α-methyl-6-methoxy-2-naphthylacetic acid, is an important non-steroidal anti-inflammatory drug [1], [2]

The inversion of the chiral centers in (R)/(S)-naproxen–(S)-tryptophan linked system under UV irradiation has been detected by the 1 H NMR spectroscopy as an example of the (CH2) proton at the chiral center of diastereomer (R,S)-1 was carried out on the assumption that this signal represents superposition of CH protons from both
The two structures have the same molecular formula and the same connectivity, therefore they must be stereoisomers
