A series of α-diimine Ni(II) complexes containing bulky phenyl groups, [ArN = C(Naphth)C = NAr]NiBr2 (Naphth: 1,8-naphthdiyl, Ar = 2,6-Me2-4-PhC6H2 (C1); Ar = 2,4-Me2-6-PhC6H2 (C2); Ar = 2-Me-4,6-Ph2C6H2 (C3); Ar = 4-Me-2,6-Ph2C6H2 (C4); Ar = 4-Me-2-PhC6H3 (C5); Ar = 2,4,6-Ph3C6H2 (C6)), were synthesized and characterized. Upon activation with either diethylaluminum chloride (Et2AlCl) or modifi...

Alkylresorcinols (AR) are phenolic lipids found in high amounts in wholegrain wheat and rye. They may be important as bioactive components and/or biomarkers of wholegrain wheat and rye intake. AR absorption was studied with pigs during a habitual diet and after a single meal of AR-rich diet. In study 1, four pigs were fed wholegrain rye (RD) and white wheat bread (WD) for 1 week in a cross-over...

Nearly 20 different transcripts of the human androgen receptor (AR) are reported with two currently listed as Refseq isoforms in the NCBI database. Isoform 1 encodes wild-type AR (type 1 AR) and isoform 2 encodes the variant AR45 (type 2 AR). Both variants contain eight exons: they share common exons 2-8 but differ in exon 1 with the canonical exon 1 in isoform 1 and the variant exon 1b in isof...

Objectives: The regulation of cardiac function by catecholamines involves three populations of b-adrenoceptor (b-AR). b and b -AR 1 2 stimulations produce an increase in contractility and b -AR stimulation mediates a negative inotropic effect in human ventricular muscle. 3 Because of the lack of suitable animal models, we have generated transgenic mice with cardiac-specific expression of the hu...

Castration-recurrent prostate cancer (CRPC) is suspected to depend on androgen receptor (AR). The AF-1 region in the amino-terminal domain (NTD) of AR contains most, if not all, of the transcriptional activity. Here we identify EPI-001, a small molecule that blocked transactivation of the NTD and was specific for inhibition of AR without attenuating transcriptional activities of related steroid...

An agonist-occupied beta(2)-adrenergic receptor (beta(2)-AR) recruits G protein receptor kinase-2 (GRK2) which is recruited to the membrane. Thus, the physical proximity of activated beta(2)-AR and PI-3K allows the activation of the latter. In contrast, it has been observed that the beta(1)-AR is unable to activate the PI-3K/Akt pathway. We hypothesized that the difference might be due to molec...

OBJECTIVES Free ritonavir, lopinavir and efavirenz injected intraperitoneally were compared with antiretroviral (AR) nanoparticles (NPs). METHODS This is a prospective study in BALB/c mice comparing the pharmacokinetics of free drugs with AR NPs. All animals received free drugs or AR NPs (20 mg/kg) in PBS. In vitro replication assays were used for determination of the anti-HIV efficacy of NP ...

The structure and ground state dynamics of the atom–diatom dimer interaction between Ar and HI has been investigated by microwave and near infrared supersonic jet spectroscopy. Ab initio molecular orbital calculations were used to provide greater insight into the nature of the interaction. The ground state is shown to be in the isomeric form Ar–IH with Rcm53.9975(1) Å, u 5149.33(1)° for the nor...

We have recently demonstrated protection against renal ischemic-reperfusion injury in vivo by A(1)- and A(2a)-adenosine receptor (AR) modulations. To further elucidate the signaling cascades of AR-induced cytoprotection against reperfusion/oxidant-mediated injury, immortalized human proximal tubule (HK-2) cells were treated with H(2)O(2). H(2)O(2) caused dose- and time-dependent HK-2 cell death...

We compared DNA replication, protein biosynthesis, and mitogen-activated protein kinase (MAPK) activity in Rat 1 fibroblasts stably expressing either the 1B-adrenergic receptor (AR) or 1D-AR subtypes. Activation of both the 1B-AR and 1D-AR inhibited DNA synthesis (as assessed by [H]thymidine incorporation). In contrast, both receptors stimulated protein biosynthesis (as measured by [S]methionin...
