Oil from the wild roots of North India is said to be highly levorotatory (rotates the plane of polarized light to the left), whereas that from the cultivated roots from South India is dextrorotatory (rotates polarized light to the right).    From Wordnik.com.  [4 Questions and Answers] Reference

It was found chemically that cane sugar absorbs the elements of water and changes into a mixture of two different sugars, one being weakly dextrorotatory and the other strongly laevorotatory, hence the resultant is a rotation to the left.    From Wordnik.com.  [Wilhelm Ostwald - Nobel Lecture] Reference

The '265 patent discusses the unusual stereoselectivity of the biological properties as between the dextrorotatory and the levorotatory enantiomers.    From Wordnik.com.  [Patent Baristas] Reference

This appeal is focused on the question of patentability of this dextrorotatory isomer in view of its known racemate described in earlier Sanofi patents, specifically, Sanofi's.    From Wordnik.com.  [Patent Baristas] Reference

Clopidogrel is the common name of the dextrorotatory isomer of the chemical compound named methyl alpha-5 (4,5,6,7-tetrahydro (3,2-c) thienopyridyl) (2-chlorophenyl) - acetate.    From Wordnik.com.  [Patent Baristas] Reference

Apotex argued that the recognition in the prior art that PCR 4099 is composed of enantiomers outweighs the effect of any unexpected or unpredictable properties of the separated dextrorotatory enantiomer.    From Wordnik.com.  [Patent Baristas] Reference

In this case the district court said the references 'general statements that these compounds consist of enantiomers didn't make an anticipating disclosure of the separated dextrorotatory enantiomer of PCR 4099.    From Wordnik.com.  [Patent Baristas] Reference

As if that were not enough to ensure the longevity of refreshingly ordinary words like clockwise, further along the avenues of science we come across the adjectives dextrorotatory or dextrorotatary, dextrogyrous, dextrogyrate and dextrogyre.    From Wordnik.com.  [VERBATIM: The Language Quarterly Vol IX No 3] Reference

The district court did not clearly err in finding that the statements in the '596 patent and its Canadian counterpart that the products therein consist of enantiomers are not a description of the specific dextrorotatory enantiomer clopidogrel or a suggestion of its unusual stereospecific properties.    From Wordnik.com.  [Patent Baristas] Reference

Believing that there was no advantage to separation of the enantiomers of thienopyridines, and no other racemates were separated until November 1985 when Sanofi then determined the biological properties of the enantiomers of PCR 4099, and found that they had the rare characteristic of "absolute stereoselectivity": the dextrorotatory enantiomer provided all of the favorable antiplatelet activity but with no significant neurotoxicity, while the levorotatory enantiomer produced no antiplatelet activity but virtually all of the neurotoxicity.    From Wordnik.com.  [Patent Baristas] Reference
