Sesquiterpene lactones. XXIII. Isolation of sesquiterpene lactones from Centaurea L. species
Acta Societatis Botanicorum Poloniae, 2014 Sesquiterpene lactones were isolated from 18 species or subspecies of the genus <em>Centaurea L.</em>: salonitenolide (I) was found in <em>C. crithmifolia Vis., C. friderici Vis., C, paniculata L., C. calcitrapa L., C. pontica </em>Prodan et E. L' Nyarady, <em>C. eriophora L., C. alba L. subsp.

Plants, Pollinators and Pheromones: Promises and Lies of Semiochemicals
Plant, Cell &Environment, EarlyView.ABSTRACT Pollination is traditionally regarded as a quintessential mutualism, yet many plants employ deceptive strategies to achieve reproductive success. Among the most intriguing is sexual deception, wherein flowers mimic the sex pheromones and visual signals of female insects to attract male pollinators—without providing any reward.

In silico investigation of lactone and thiolactone inhibitors in bacterial quorum sensing using molecular modeling [PDF]
arXiv, 2013 In the present study, the origin of the anti-quorum sensing (QS) activities of several members of a recently synthesized and in vitro tested class of lactone and thiolactone based inhibitors were computationally investigated. Docking and molecular dynamic (MD) simulations and binding free energy calculations were carried out to reveal the exact binding
