Piperlongumine and p53-reactivator APR-246 selectively induce cell death in HNSCC by targeting GSTP1

TP53 mutations frequently occur in head and neck squamous cell carcinoma (HNSCC) patients without human papillomavirus infection. The recurrence rate for these patients is distinctly high. It has been actively explored to identify agents that target TP53 mutations and restore wild-type (WT) TP53 activities in HNSCC. PRIMA-1 (p53-reactivation and induction of massive apoptosis-1) and its methylated analogue PRIMA-1Met (also called APR-246) were found to be able to reestablish the DNA-binding activity of p53 mutants and reinstate the functions of WT p53. Herein we report that piperlongumine (PL), an alkaloid isolated from Piper longum L., synergizes with APR-246 to selectively induce apoptosis and autophagic cell death in HNSCC cells, whereas primary and immortalized mouse embryonic fibroblasts and spontaneously immortalized non-tumorigenic human skin keratinocytes (HaCat) are spared from the damage by the co-treatment. Interestingly, PL-sensitized HNSCC cells to APR-246 are TP53 mutation-independent. Instead, we demonstrated that glutathione S-transferase pi 1 (GSTP1), a GST family member that catalyzes the conjugation of GSH with electrophilic compounds to fulfill its detoxification function, is highly expressed in HNSCC tissues. Administration of PL and APR-246 significantly suppresses GSTP1 activity, resulting in the accumulation of ROS, depletion of GSH, elevation of GSSG, and DNA damage. Ectopic expression of GSTP1 or pre-treatment with antioxidant N-acetyl-l-cysteine (NAC) abrogates the ROS elevation and decreases DNA damage, apoptosis, and autophagic cell death prompted by PL/APR-246. In addition, administration of PL and APR-246 impedes UMSCC10A xenograft tumor growth in SCID mice. Taken together, our data suggest that HNSCC cells are selectively sensitive to the combination of PL and APR-246 due to a remarkably synergistic effect of the co-treatment in the induction of ROS by suppression of GSTP1.

Synthesis and biological activities of indolizine derivatives as alpha-7 nAChR agonists

Human alpha7 nicotinic acetylcholine receptor (nAChR) is a promising therapeutic target for the treatment of schizophrenia accompanied with cognitive impairment. Herein, we report the synthesis and agonistic activities of a series of indolizine derivatives targeting to alpha7 nAChR. The results show that all synthesized compounds have affinity to alpha7 nAChR and some give strong agonistic activity, particularly most active agonists show higher potency than control EVP-6124. The docking and structure-activity relationship studies provide insights to develop more potent novel alpha7 nAChR agonists.

Muscarinic contraction in isolated guinea-pig trachea and antagonism by noradrenaline

In contrast to other muscarinic agonists, WAL 2014 FU does not induce bronchospasm in laboratory animals. The present investigation was intended to test the hypothesis that this is due to a particular susceptibility of the drug’s effect to antagonism by catecholamines, as a result of partial M3- agonism. The tonic activity of the muscarinic agonists, aceclidine, arecoline, carbachol, McN-A-343, RS 86, thiopilocarpine and WAL 2014 FU, was tested in groups of isolated tracheal muscle of the guinea-pig. Susceptibility to functional antagonism by beta-adrenoceptor stimulation was measured by the displacement of the concentration-force curves by 3 muM noradrenaline. Evaluation of the concentration-force relationship revealed differences in potency and intrinsic activity (carbachol=100%) ranging from 114% for arecoline to 36% for thiopilocarpine (WAL 2014 FU=63%). The catecholamine increased the concentration of agonist which induced 5% of the maximum effect achievable (EC05) values fivefold (carbachol) to more than 4,680 fold (thiopilocarpine) (WAL 2014 FU: 2,860 fold). Regression analysis between the intrinsic activity of the seven compounds and the antagonistic effect of noradrenaline revealed a significant correlation (Spearman correlation coefficient (r(s)) =-0.79; p=0,036). Inhibition of the effects of endogenous catecholamines by beta-adrenolysis with 50 muM toliprolol increased the maximal contraction induced by 1 mM WAL 2014 FU, but did not affect maximal contraction induced by 30 muM arecoline. Pretreatment with 0.3-1.0 mM dibutyrylcyclic adenosine monophosphate (DBcAMP) shifted the concentration- response curves of arecoline, WAL 2014 FU and thiopilocarpine in a similar manner to noradrenaline. The results exclude an important contribution of adenylate cyclase-coupled M2-receptors to the susceptibility of tracheal contraction by muscarinic agonists to functional antagonism by noradrenaline, but emphasize the importance of intrinsic activity at the M3-receptors. The pronounced susceptibility of WAL 2014 FU-induced contraction to functional antagonism by beta-adrenoceptor activation provides an explanation for the failure of the drug to induce bronchospasm in vivo.

Muscarinic effects on cellular functions in cultured human ciliary muscle cells

Purpose. To characterize the pharmacology of the carbachol-induced changes of phospholipase C (PLC) activity and intracellular calcium concentration ([Ca2+](i)) in cultured human ciliary muscle cells. Methods. Changes in PLC activity of cultured human ciliary muscle cells were determined by production of inositol phosphates. Single-cell dynamic fluorescence ratio imaging was used to determine [Ca2+](i). Results. Carbachol, oxotremorine-M, aceclidine, and pilocarpine stimulated PLC with mean EC50s of 20, 8, 17, and 2 muM, respectively. The effect of carbachol on PLC was partially suppressed by extracellular Ca2+ depletion. This muscarinic effect was blocked by muscarinic antagonists, such as atropine (apparent pK(i) = 9.12, nonselective for muscarinic receptor subtypes), pirenzepine (pK(i) = 6.76, selective for the M1 receptor subtype), 4DAMP (pK(i) = 9.25, selective for the M1 and M3 subtypes), and fHHSiD (pK(i) = 7.77, selective for the M3 subtype). In [Ca2+](i) experiments, carbachol increased [Ca2+](i) transients in human ciliary muscle cells in a dose-dependent manner with a mean EC50 of 7 muM. 4DAMP was approximately 100 times more potent than pirenzepine in the inhibition of the carbachol-induced [Ca2+](i) increase. [Ca2+](i) oscillations were observed after carbachol stimulation and persisted after extracellular Ca2+ depletion. Conclusions. Muscarinic agonists activate PLC and increase [Ca2+](i) in cultured human ciliary muscle cells through an M3-like muscarinic receptor subtype.

Design of alpha7 nicotinic acetylcholine receptor ligands using the (het)Aryl-1,2,3-triazole core: Synthesis, in vitro evaluation and SAR studies

We report here the synthesis of a large library of 1,2,3-triazole derivatives which were in vitro tested as alpha7 nAchR ligands. The SAR study revealed that several crucial factors are involved in the affinity of these compounds for alpha7 nAchR such as a (R) quinuclidine configuration and a mono C-3 quinuclidine substitution. The triazole ring was substituted by a phenyl ring bearing small OMe/CH2F groups or fluorine atom and by several heterocycles such as thiophenes, furanes, benzothiophenes or benzofuranes. Among the 30 derivatives tested, the two derivatives 10 and 39 with Ki in the nanomolar range were identified (2.3 and 3 nM respectively). They exhibited a strict selectivity toward the alpha4beta2 nicotinic receptor (up to 1 muM) but interacted with the 5HT3 receptors with Ki around 3 nM. Synthesis, SAR studies and a full description of the derivatives are reported.

Development of (4-Cyanophenyl)glycine Derivatives as Reversible Inhibitors of Lysine Specific Demethylase 1

Inhibition of lysine specific demethylase 1 (LSD1) has been shown to induce the differentiation of leukemia stem cells in acute myeloid leukemia (AML). Irreversible inhibitors developed from the nonspecific inhibitor tranylcypromine have entered clinical trials; however, the development of effective reversible inhibitors has proved more challenging. Herein, we describe our efforts to identify reversible inhibitors of LSD1 from a high throughput screen and subsequent in silico modeling approaches. From a single hit (12) validated by biochemical and biophysical assays, we describe our efforts to develop acyclic scaffold-hops from GSK-690 (1). A further scaffold modification to a (4-cyanophenyl)glycinamide (e.g., 29a) led to the development of compound 32, with a Kd value of 32 nM and an EC50 value of 0.67 muM in a surrogate cellular biomarker assay. Moreover, this derivative does not display the same level of hERG liability as observed with 1 and represents a promising lead for further development.
