Quantifying biogenic bias in screening libraries. [PDF]

open access: yes, 2009
In lead discovery, libraries of 10(6) molecules are screened for biological activity. Given the over 10(60) drug-like molecules thought possible, such screens might never succeed.

Direct imaging of carbohydrate stereochemistry [PDF]

open access: yesarXiv
Carbohydrates, essential biological building blocks, exhibit functional mechanisms tied to their intricate stereochemistry. Subtle stereochemical differences, such as those between the anomers maltose and cellobiose, lead to distinct properties due to their differing glycosidic bonds; the former is digestible by humans, while the latter is not.

Improving physical realism, stereochemistry, and side‐chain accuracy in homology modeling: Four approaches that performed well in CASP8

open access: yesProteins: Structure, Function, and Bioinformatics, 2009
A correct alignment is an essential requirement in homology modeling. Yet in order to bridge the structural gap between template and target, which may not only involve loop rearrangements, but also shifts of secondary structure elements and repacking of ...

Optically active beams: non-reciprocal optical activity in free space induced by spin-orbital interaction of light [PDF]

open access: yesarXiv, 2019
Optical activity, the power of a medium to rotate the polarization of a light beam, has contributed significantly to molecular structure assessments in stereochemistry, biomolecular science and crystallography. Thus far, it is commonly believed that optical activity is manifested only in the chiral media which can give rise to circular birefringence of

Advancing peptide siRNA-carrier designs through L/D-amino acid stereochemical modifications to enhance gene silencing

open access: yesMolecular Therapy: Nucleic Acids, 2021
The 599 peptide has been previously shown to effectively deliver small interfering RNAs (siRNAs) to cancer cells, inducing targeted-oncogene silencing, with a consequent inhibition of tumor growth. Although effective, this study was undertaken to advance

Five-membered ring annelation in [2.2]paracyclophanes by aldol condensation

open access: yesBeilstein Journal of Organic Chemistry, 2014
Under basic conditions 4,5,12,13-tetraacetyl[2.2]paracyclophane (9) cyclizes by a double aldol condensation to provide the two aldols 12 and 15 in a 3:7 ratio.
