Semi-Synthesis of Harringtonolide Derivatives and Their Antiproliferative Activity

open access: yesMolecules, 2021
Harringtonolide (HO), a natural product isolated from Cephalotaxus harringtonia, exhibits potent antiproliferative activity. However, little information has been reported on the systematic structure−activity relationship (SAR) of HO derivatives ...

Synthesis, antimicrobial screening and structure–activity relationship of novel pyrimidines and their thioethers

open access: yesBulletin of Faculty of Pharmacy Cairo University, 2014
In the present study, a series of novel pyrimidines (1) and their thioethers (2–5) were synthesized. Structures of the synthesized compounds were established by IR, 1H NMR, 13C NMR mass spectral data and elemental analysis.

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

open access: yesPopulation Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Network topology drives population temporal variability in experimental habitat networks

open access: yesPopulation Ecology, EarlyView.
Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

Design, Synthesis, and Biological Evaluation of 8-Mercapto-3,7-Dihydro-1H-Purine-2,6-Diones as Potent Inhibitors of SIRT1, SIRT2, SIRT3, and SIRT5

open access: yesMolecules, 2020
Sirtuins (SIRT1-7) are a family of NAD+-dependent deacetylases. They regulate many physiological processes and play important roles in inflammation, diabetes, cancers, and neurodegeneration diseases.
