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 ...

Quantitative structure-activity relationship for antimalarial activity of artemisinin [PDF]

open access: yes, 2010
The increase in resistance to older drugs and the emergence of new types of infection have created an urgent need for discovery and development of new compounds with antimalarial activity.

Classification Framework and Structure-Activity-Relationship (SAR) of Tetracycline-Structure-Based Drugs

open access: yes, 2012
By studying the literature about Tetracyclines (TCs), it becomes clearly evident that TCs are very dynamic molecules. In some cases, their structure-activity-relationship (SAR) are known, especially against bacteria, while against other targets, they are

Global Antifungal Profile Optimization of Chlorophenyl Derivatives against Botrytis cinerea and Colletotrichum gloeosporioides [PDF]

open access: yes, 2009
Twenty-two aromatic derivatives bearing a chlorine atom and a different chain in the para or meta position were prepared and evaluated for their in vitro antifungal activity against the phytopathogenic fungi Botrytis cinerea and Colletotrichum ...

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 ...

Electrochemical behavior of indolone-N-oxides: Relationship to structure and antiplasmodial activity [PDF]

open access: yes, 2012
Indolone-N-oxides exert high parasiticidal activity at the nanomolar level in vitro against Plasmodiumfalciparum, the parasite responsible for malaria.

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 ...

Current Research on Antiepileptic Compounds

open access: yesMolecules, 2015
Epilepsy affects about 1% of the world’s population. Due to the fact all antiepileptic drugs (AEDs) have some undesirable side effects and about 30% of epileptic patients are not seizure-free with the existing AEDs, there is still an urgent need for the ...

Structure-based discovery of fiber-binding compounds that reduce the cytotoxicity of amyloid beta. [PDF]

open access: yes, 2013
Amyloid protein aggregates are associated with dozens of devastating diseases including Alzheimer's, Parkinson's, ALS, and diabetes type 2. While structure-based discovery of compounds has been effective in combating numerous infectious and metabolic ...
