Background on 4-IBP

4-IBP is a selective σ1 agonist with a high level of affinity for the σ1 receptor (Ki = 1.7 nM) and a moderate affinity for the σ2 receptor (Ki = 25.2 nM) . IC50 value: 1.7 nM (Ki) Target: σ1 in vitro: 4-IBP is a σ1 receptor agonist, decreases the migration of human cancer cells, including glioblastoma cells. 4-IBP is used to investigate whether targeting theσ1 receptor could modify in vitro the migration rates of human cancer cells and increase the sensitivity of metastasizing human A549 NSCLC cells and infiltrating human glioblastoma cells to cytotoxic insults of either proapoptotic or proautophagic drugs.[1] in vivo: 4-IBP increases the antitumor effects of temozolomide and irinotecan in immunodeficient mice that were orthotopically grafted with invasive cancer cells.[1]

4-IBP, a sigma1 receptor agonist, decreases the migration of human cancer cells, including glioblastoma cells, in vitro and sensitizes them in vitro and in vivo to cytotoxic insults of proapoptotic and proautophagic drugs.[Pubmed:17534441]

Neoplasia. 2007 May;9(5):358-69.

Although the molecular function of sigma receptors has not been fully defined and the natural ligand(s) is still not known, there is increasing evidence that these receptors and their ligands might play a significant role in cancer biology. 4-(N-benzylpiperidin-4-yl)-4-iodobenzamide (4-IBP), a selective sigma1 agonist, has been used to investigate whether this compound is able to modify: 1) in vitro the migration and proliferation of human cancer cells; 2) in vitro the sensitivity of human glioblastoma cells to cytotoxic drugs; and 3) in vivo in orthotopic glioblastoma and non-small cell lung carcinoma (NSCLC) models the survival of mice co-administered cytotoxic agents. 4-IBP has revealed weak antiproliferative effects on human U373-MG glioblastoma and C32 melanoma cells but induced marked concentration-dependent decreases in the growth of human A549 NSCLC and PC3 prostate cancer cells. The compound was also significantly antimigratory in all four cancer cell lines. This may result, at least in U373-MG cells, from modifications to the actin cytoskeleton. 4-IBP modified the sensitivity of U373-MG cells in vitro to proapoptotic lomustin and proautophagic temozolomide, and markedly decreased the expression of two proteins involved in drug resistance: glucosylceramide synthase and Rho guanine nucleotide dissociation inhibitor. In vivo, 4-IBP increased the antitumor effects of temozolomide and irinotecan in immunodeficient mice that were orthotopically grafted with invasive cancer cells.

Modulation of serotonergic neurotransmission by short- and long-term treatments with sigma ligands.[Pubmed:11588125]

Br J Pharmacol. 2001 Oct;134(3):691-9.

1. Sigma receptors were first described in 1976 as opiate receptors but were later determined to be a distinct class of receptors with two subtypes, sigma(1) and sigma(2). Although the endogenous ligand is yet to be elucidated, the sigma(1) receptor has recently been cloned. 2. Behavioural models used to test potential antidepressants have shown sigma ligands to produce antidepressant effects but their mechanism of action is unknown. 3. The goal of the present study was to assess the effects of various sigma(1) ligands on the firing activity of serotonin (5-HT) neurons of the dorsal raphe nucleus (DRN) using extracellular in vivo recordings in anaesthetized rats. 4. The sigma(1) ligands (+)-pentazocine and 4-(N-benzylpiperidin-4-yl)-4-iodobenzamide (4-IBP) (2 mg kg(-1) day(-1)) increased markedly 5-HT firing activity after 2 days of treatment and maintained the same increased firing rate after long-term (21 days) treatments. Furthermore, the increased firing rate produced by 2 and 21 day treatments with (+)-pentazocine was prevented by the co-administration of N,N-dipropyl-2-(4-methoxy-3-(2-phenylethoxy)phenyl)-thylamine (NE-100) (10 mg kg(-1) day(-1)) a selective sigma(1) antagonist, confirming the sigma(1) receptor's modulation of these effects. In contrast, the sigma(1) ligands (+)-N-cyclopropylmethyl-N-methyl-1,4-diphenyl-1-1-ethyl-but-3-en-1-ylamine hydrochloride (JO-1784) and 2-(4-morpholinoethyl 1-phenyl-cyclohexane-1-carboxylate hydrochloride (PRE-084) had no effect. 5. Following a 21-day treatment with (+)-pentazocine there was a marked reduction in the number of neurons found per track. This decrease was not seen after chronic treatment with 4-IBP and may represent a depolarization block. 6. These results suggest a modulation of serotonergic neurotransmission by some sigma receptors and provide a potential mechanism for the 'antidepressant effects' reported and provide evidence toward sigma(1) ligands as potential antidepressants with a rapid onset of action.

Antagonism of N-methyl-D-aspartate receptors by sigma site ligands: potency, subtype-selectivity and mechanisms of inhibition.[Pubmed:9223571]

J Pharmacol Exp Ther. 1997 Jul;282(1):326-38.

Recent studies propose that sigma site ligands antagonize N-methyl-D-aspartate (NMDA) receptors by either direct, or indirect mechanisms of inhibition. To investigate this question further we used electrical recordings to assay actions of seventeen structurally diverse sigma site ligands on three diheteromeric subunit combinations of cloned rat NMDA receptors expressed in Xenopus oocytes: NR1a coexpressed with either NR2A, 2B or 2C. The sigma site ligands had a wide range of potency for antagonizing NMDA receptor currents. Steady-state IC50 values ranged between approximately 0.1 to >100 microM. In all cases inhibition was non-competitive with respect to glycine and glutamate. Five structurally related sigma ligands [eliprodil, haloperidol, ifenprodil, 4-phenyl-1-(4-phenylbutyl)-piperidine and trifluperidol] were strongly selective for NR1a/2B receptors. The other drugs were weakly selective or nonselective inhibitors. There was no correlation between sigma site affinity and potency of NMDA receptor antagonism for any subunit combination. Inhibition of NR1a/2B receptors by the selective antagonists was independent of voltage whereas inhibition by the weakly selective antagonists was voltage dependent. Potency of 10 sigma ligands was cross-checked on NMDA currents in cultured rat cortical neurons. There was close correspondence between the two assay systems. Our results argue that antagonism of NMDA receptor currents by the sigma ligands tested is due to direct effects on the receptor channel complex as opposed to indirect effects mediated by sigma receptors. Inhibition occurs via sites in the NMDA receptor channel pore, or via allosteric modulatory sites associated with the NR2B subunit.
