“The roots of Mirabilis jalapa are used traditionally in allergic skin disorders and asthma. The

effect of an ethanol : acetone (1 : 1) extract of the roots of M. jalapa was studied for antihistaminic activity using a guinea pig tracheal chain preparation and clonidine-induced mast cell granulation in mice. Its antiallergic activity was evaluated using milk-induced eosinophilia and albumin-induced paw oedema in mice. The extract (0.5 mL of 100 mg mL-1) inhibited histamine-induced guinea pig tracheal chain contractions non-competitively. Cytoskeletal Signaling inhibitor The extract (100 or 200 mg kg-1 i.p.) inhibited milk-induced eosinophilia, albumin-induced paw oedema and protected mast cells against clonidine-induced granulation. The study justified the folkloric use of M. jalapa in the treatment of allergic diseases and asthma.”
“Atherosclerosis of the internal mammary artery (IMA) is

generally regarded as a rare (but existent) pathological entity with only a few cases reported in the most recent literature. The only study which to our knowledge has investigated the ultrastructural features of IMA atherosclerosis, demonstrate the presence of endothelial cells loss, defects of internal elastic lamina with no evidence of lipid accumulation. In the present study, we describe two cases of IMA atherosclerosis in which ultrastructural analysis revealed the presence of a typical Dibutyryl-cAMP price atherosclerotic plaque morphology with infiltration of inflammatory cells, formation of intraplaque lipid pools, and accumulation of lipid-laden foam cells Crenigacestat clinical trial throughout the thickened intima, never described in this rare lesion before. Microscopically, the lesions were also characterized by intimal thickening, invagination of endothelial cells, migration of smooth muscle cells with splitting, fenestration and/or fragmentation of the elastic sheets. Our observations add new data to the scarce and contradictory literature and to this largely understudied vascular disorder.”
“Two new tirucallane triterpenoids, 21-methoxy-21,23-epoxy-tirucalla-7,24-dien-3 alpha-ol (1) and 21-methoxy-21,23-epoxy-tirucalla-7,24-diene-1 alpha,3 alpha-diol (2), together with thirteen known compounds were isolated from

the CH2Cl2 extract of the stem bark of Araliopsis synopsis. The structures of the compounds were determined by comprehensive analyses of their 1D and 2D NMR, mass spectral (EI and ESI) data and comparison with previously known analogs. Compounds 1-10 were tested against bacteria, fungi and plant pathogen oomycetes by the paper disk agar diffusion assay resulting in missing to low activities corresponding with MICs > 1 mg/mL. However, compounds 5-10 exhibited high cytotoxic activity against the human Caucasian prostate adenocarcinoma cell PC-3 line, with IC50 8.5-12.5 mu M compared to the standard Doxorubicin with IC50 = 0.9 mu M, while compounds 1, 3 and 4 showed low activity.
