Efficacy of glutathione inhibitors for the treatment of ARID1A-deficient diffuse-type gastric cancers

ARID1A, a subunit of the SWI/SNF chromatin remodeling complex, increases the intracellular levels of glutathione (GSH) by upregulating solute carrier family 7 member 11 (SLC7A11). Diffuse-type gastric cancer is an aggressive tumor that is frequently associated with ARID1A deficiency. Here, we investigated the efficacy of GSH inhibition for the treatment of diffuse-type gastric cancer with ARID1A deficiency using ARID1A-proficient or -deficient patient-derived cells (PDCs). ARID1A-deficient PDCs were selectively sensitive to the GSH inhibitor APR-246, the GCLC inhibitor buthionine sulfoximine, and the SLC7A11 inhibitor erastin. Expression of SLC7A11, which is required for incorporation of cystine, and the basal level of GSH were lower in ARID1A-deficient than in ARID1A-proficient PDCs. Treatment with APR-246 decreased intracellular GSH levels, leading to the excessive production of reactive oxygen species (ROS), and these phenotypes are suppressed by supply of cystine and GSH compensators. Taken together, vulnerability of ARID1A-deficient gastric cancer cells to GSH inhibition is caused by decreased GSH synthesis due to diminished SLC7A11 expression. The present results suggest that GSH inhibition is a promising strategy for the treatment of diffuse-type gastric cancers with ARID1A deficiency.

Estimation of agonist activity at g protein-coupled receptors: Analysis of M2 muscarinic receptor signaling through Gi/o, G s, and G15

We developed novel methods for analyzing the concentrationresponse curve of an agonist to estimate the product of observed affinity and intrinsic efficacy, expressed relative to that of a standard agonist. This parameter, termed intrinsic relative activity (RAi), is most applicable for the analysis of responses at G protein-coupled receptors. RAi is equivalent to the potency ratios that agonists would exhibit in a hypothetical, highly sensitive assay in which all agonists behave as full agonists, even those with little intrinsic efficacy. We investigated muscarinic responses at the M2 receptor, including stimulation of phosphoinositide hydrolysis through Galpha15 in HEK 293T cells, inhibition of cAMP accumulation through Gi in Chinese hamster ovary (CHO) cells, and stimulation of cAMP accumulation through Gs in CHO cells treated with pertussis toxin. The RAi values of carbachol, oxotremorine-M, and the enantiomers of aceclidine were approximately the same in the three assay systems. In contrast, the activity of 4-[[N-[3-chlorophenyl]carbamoy] oxy-2-butynyl]trimethylammonium chloride (McN-A-343) was ?10-fold greater at M2 receptors coupled to Galpha15 in HEK 293T cells compared with M2 receptors coupled to Gi in the same cells or in CHO cells. Our results show that the RAi estimate is a useful measure for quantifying agonist activity across different assay systems and for detecting agonist directed signaling. Copyright

In vitro muscarinic activity of spiromuscarones and related analogs

The cholinergic hypothesis of Alzheimer’s disease suggests that cholinergic agonists may have therapeutic potential for treating the attendant memory deficits of the disease. As part of a program aimed at preparing metabolically stable, nonquaternary analogs of muscarone, 1-oxa- 2,8-dimethyl-8-azaspiro[4.5]decan-3-one, 2a, and related analogs have been synthesized and their in vitro muscarinic activity evaluated. The synthetic strategy in the formation of the 1-spiro[4.5]decan-3-one ring system of 2a involved cyclization of the diol 4 in the presence of Nafion-Hg. The spiromuscarone 2a was found to displace [3H]Oxo-M binding with a K(i) value of 7 nM. Affinities of the oxime and hydrazone analogs of 2a were lower than 2a. The compounds in these series were partial muscarinic agonists as demonstrated by stimulation of phosphatidyl inositol hydrolysis assay, with 2a showing the highest intrinsic activity (60% as compared with carbachol). The results from this study indicate that an exo double bond at the C-3 position is essential for the receptor binding.

PRIMA-1Met/APR-246 displays high antitumor activity in multiple myeloma by induction of p73 and noxa

Targeting p53 by the small-molecule PRIMA-1Met/APR-246 has shown promising preclinical activity in various cancer types.However, the mechanism of PRIMA-1Met-induced apoptosis is not completely understood and its effect on multiple myeloma cells is unknown. In this study, we evaluated antitumor effect of PRIMA-1Met alone or its combination with current antimyeloma agents in multiple myeloma cell lines, patient samples, and a mouse xenograft model. Results of our study showed that PRIMA-1Met decreased the viability of multiple myeloma cells irrespective of p53 status, with limited cytotoxicity toward normal hematopoietic cells. Treatment of multiple myeloma cells with PRIMA-1Met resulted in induction of apoptosis, inhibition of colony formation, and migration. PRIMA-1Met restored wild-type conformation of mutant p53 and induced activation of p73 upregulating Noxa and downregulating Mcl-1 without significant modulation of p53 level. siRNAmediated silencing of p53 showed a little effect on apoptotic response of PRIMA-1Met, whereas knockdown of p73 led to substantial attenuation of apoptotic activity in multiple myeloma cells, indicating that PRIMA-1Met- induced apoptosis is, at least in part, p73-dependent.Importantly, PRIMA-1Met delayed tumor growth and prolonged survival of mice bearing multiple myeloma tumor. Furthermore, combined treatment of PRIMA-1Met with dexamethasone or doxorubicin displayed synergistic effects in both multiple myeloma cell lines and primary multiple myeloma samples. Consistent with our in vitro observations, cotreatment with PRIMA-1Met and dexamethasone resulted in enhanced antitumor activity in vivo. Our study for the first time shows antimyeloma activity of PRIMA-1Met and provides the rationale for its clinical evaluation in patients with multiple myeloma, including the high-risk group with p53 mutation/deletion.

Dual organocatalysis: Asymmetric allylic-allylic alkylation of alpha,alpha-dicyanoalkenes and Morita-Baylis-Hillman carbonates

The unprecedented asymmetric allylic-allylic alkylation of alpha,alpha-dicyanoalkenes and Morita-Baylis-Hillman (MBH) carbonates were developed by catalyzing by a suitable chiral tertiary amine. The resulting multifunctional alkylation products could also serve as versatile intermediates for other synthetic transformations. The analogous catalysts show no catalytic activity in the model reaction due to steric activity. The alkylation reaction could be conducted at higher temperature in 1,2-dichloroethane (DCE) with little effect on the enantioselectivity. Excellent results are obtained by employing two equivalents of the MBH adduct and when 10% mol of (R)-BINOL is used. Mixtures of mono and double-allylic alkylation products are formed when symmetric alpha,alpha-dicyanoalkenes are applied. It is also found that the double-allylic alkylation adducts with four stereogenic centers could be isolated as single diasteromers with remarkable ee values.
