Discovery of (S)-3′-hydroxyblebbistatin and (S)-3′-aminoblebbistatin : polar myosin II inhibitors with superior research tool properties [PDF]
, 2017 In search of myosin II inhibitors with superior research tool properties, a chemical optimization campaign of the blebbistatin scaffold was conducted in this paper. (S)-Blebbistatin is the best known small-molecule inhibitor of myosin II ATPase activity.

Total Chiral Symmetry Breaking during Crystallization: Who needs a "Mother Crystal"? [PDF]
, 2005 Processes that can produce states of broken chiral symmetry are of particular interest to physics, chemistry and biology. Chiral symmetry breaking during crystallization of sodium chlorate occurs via the production of secondary crystals of the same ...

Uni-directional polymerization leading to homochirality in the RNA world [PDF]
, 2005 The differences between uni-directional and bi-directional polymerization are considered. The uni-directional case is discussed in the framework of the RNA world. Similar to earlier models of this type, where polymerization was assumed to proceed in a bi-

High Throughput Enzymatic Enantiomeric Excess: Quick-ee
Journal of the Brazilian Chemical Society, 2014 High throughput techniques to evaluate enantiomeric excess (ee) and enantiomeric ratio (E) of enzymatic reactions are fast and efficient tools that can be applied large quantities of enzymes, microorganisms and clones. The Quick-ee technique proposed in this study produces the ee and conversion values separately.
