Here we report that a novel synthesized compound (E)-2-methoxy-4-(3-(4-methoxyphenyl)prop-1-en-1-yl)phenol (MMPP) which exhibits better stability, drug-likeness and anti-cancer effect than (E)-2,4-bis(p-hydroxyphenyl)-2-butenal (BHPB) that we previously reported. Of all newly synthesized BHPB analogues, MMPP showed the most significant inhibitory effect on colon cancer cell growth. Thus, we evaluated the anti-cancer effects and possible mechanisms of MMPP and .

Chemokine receptors are implicated in inflammation and immune responses. Neuro-inflammation is associated with activation of astrocyte and amyloid-beta (Aβ) generations that lead to pathogenesis of Alzheimer disease (AD). Previous our study showed that deficiency of CC chemokine receptor 5 (CCR5) results in activation of astrocytes and Aβ deposit, and thus memory dysfunction through increase of CC chemokine receptor 2 (CCR2) expression.

Naphthofuran compounds have been known to regulate HNF 4α which is associated with proliferation, progression and metastasis of HCC. In this study, we investigated whether N-(3,5-bis(trifluoromethyl)phenyl)-5-chloro-2,3-dihydronaphtho[1,2-b]furan-2-carboxamide (NHDC), a novel synthetic naphthofuran compound inhibits liver tumor growth through activation of HNF 4α. Treatment with different concentrations (1-10.

Estrogen has been known to reduce the development of Alzheimer's disease (AD). However, exact mechanisms are not clear. We investigated whether estrogen can increase amyloid-beta (Aβ) degradation and affects Aβ-induced memory impairment in an estrogen deficiency model.

Background: ent-Sauchinone is a polyphenolic compound found in plants belonging to the lignan family. ent-Sauchinone has been shown to modulate the expression of inflammatory factors through the nuclear factor-kappa B (NF-κB) signaling pathway. It is well known that neuroinflammation is associated with amyloidogenesis.

Neuroinflammation is important for the development of several neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, and stroke. Since changes of cytokine level are critical for neuroinflammation in the brain, we investigated whether IL-32α overexpression could change neuroinflammation and, thus, affect stroke development. Middle cerebral artery occlusion (MCAO) induced development of ischemia, and ischemic neuronal cell death were reduced in IL-32α-overexpressing transgenic mice (IL-32α mice) brain through the decreased release of neuroinflammatory cytokines (IL-6, IL-1β, TNF-α) and activation of astrocytes, but enhancement of anti-neuroinflammatory cytokines (IL-10).

Four crystal forms of ketorolac have been obtained by recrystallization in organic solvents under variable conditions. Different ketorolac polymorphs and pseudopolymorph were characterized by X-ray powder diffraction crystallography (XRD), Differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). In the dissolution studies in water at 37 +/- 0.
