Hydroxy-substituted trans -cinnamoyl derivatives as multifunctional tools in the context of Alzheimer's disease
摘要:
Alzheimer's disease (AD) is a multifactorial pathology that requires multifaceted agents able to address its peculiar nature. In recent years, a plethora of proteins and biochemical pathways has been proposed as possible targets to counteract neurotoxicity. Although the complex scenario is not completely elucidated, close relationships are emerging among some of these actors. In particular, increasing evidence has shown that aggregation of amyloid beta (A beta), glycogen synthase kinase 3 beta (GSK-3 beta) and oxidative stress are strictly interconnected and their concomitant modulation may have a positive and synergic effect in contrasting AD-related impairments. We designed compound 3 which demonstrated the ability to inhibit both GSK-3 beta (IC50 = 24.36 +/- 0.01 mu M) and A beta(42) self-aggregation (IC50 = 9.0 +/- 1.4 mu M), to chelate copper (II) and to act as exceptionally strong radical scavenger (k(inh) = 6.8 +/- 0.5 . 10(5) M(-1)s(-1)) even in phosphate buffer at pH 7.4 (k(inh) = 3.2 +/- 0.5 . 10(5) M(-1)s(-1)). Importantly, compound 3 showed high predicted blood-brain barrier permeability, did not exert any significant cytotoxic effects in immature cortical neurons up to 50 mu M and showed neuroprotective properties at micromolar concentration against toxic insult induced by glutamate.

develop potent and selective anti‐tumor agents, three new series of artemisinin–chalconehybrids 10a–10g, 11a–11g and 12a–12h were designed, synthesized and screened for their anti‐tumor activity against five cell lines (HT‐29, A549, MDA‐MB‐231, HeLa and H460) in vitro. Among compounds 10a–g and 11a–11g, most of them displayed enhanced activity and good selectivity toward HT‐29 and HeLa cell lines

Estrogenic compounds, compositions and method are presented. The novel estrogenic compounds comprise novel chalcone derivatives and analogs that have little or no measurable estrogen (estradiol, E2) activity but potentiate E2 activity without binding an estrogen receptor (ER). The novel compositions comprise one or more of the novel estrogenic compounds, and may optionally comprise one or more excipients. The one or more excipients may be pharmaceutically acceptable. The one or more excipients may comprise at least one compound that does not occur in nature with estrogenic compounds. The method comprises administering a pharmaceutical composition comprising an estrogenic compound described herein to a patient in need of treatment with an estrogenic compound or pharmaceutical composition.
