The pure enantiomers of the N-(2-, 3-, and 4-(2-aminocyclopropyl)phenyl)benzamides hydrochlorides 11a-j were prepared and tested against LSD1 and MAO enzymes. The evaluation of the regioisomers 11a-j highlighted a net increase of the anti-LSD1 potency by shifting the benzamide moiety from ortho to meta and mainly to para position of tranylcypromine phenyl ring, independently from their trans or cis stereochemistry. In particular, the para-substituted 11a,b (trans) and 11g,h (cis) compounds displayed LSD1 and MAO-A inhibition at low nanomolar levels, while were less potent against MAO-B. The meta analogs 11c,d (trans) and 11i,j (cis) were in general less potent, but more efficient against MAO-A than against LSD1. In cellular assays, all the para and meta enantiomers were able to inhibit LSD1 by inducing Gfi-1b and ITGAM gene expression, with 11b,c and 11g-i giving the highest effects. Moreover, 11b and 11g,h strongly inhibited the clonogenic potential of murine promyelocytic blasts.

Dublin, Dec. 20, 2016 (GLOBE NEWSWIRE) -- Research and Markets has announced the addition of the "HDAC Inhibitors Market, 2016 - 2026" report to their offering. The HDAC Inhibitors Market, 2016-2026 report was commissioned to examine the current landscape and the future outlook of the growing pipeline of products in this area. HDACs have been studied in cellular processes such as apoptosis, autophagy, metabolism, DNA damage repair, cell cycle control and senescence. Altered expression of HDACs has been observed in different tumors; this makes them a potential target for treatment of cancer and other genetic or epigenetic related disorders. Inhibition of HDACs has shown positive results in disruption of multiple cell signaling pathways and prevention of tumor growth. The study provides a detailed market forecast and opportunity analysis for the time period 2016-2026. The research, analysis and insights presented in this report include potential sales of the approved drugs and the ones in late stages of development (phase III and phase II). To add robustness to our model, we have provided three scenarios for our market forecast; these include the conservative, base and optimistic scenarios. Our opinions and insights, presented in this study were influenced by several discussions we conducted with experts in this area. All actual figures have been sourced and analyzed from publicly available information forums and primary research discussions. Financial figures mentioned in this report are in USD, unless otherwise specified. Example Highlights - Nearly 90 HDAC inhibitors are currently in clinical / preclinical stages of development; the clinical molecules account for over 30% of the pipeline while over 60% is captured by molecules in the preclinical / discovery stage. - With 66% of the pipeline molecules targeting oncological indications, cancer remains one of the most widely studied field for HDAC inhibitors. Within oncology, hematological malignancies such as PTCL and CTCL are popular targets; three HDAC inhibitors (Zolinza, ISTODAX® and BELEODAQ®) are approved for these indications. Other therapeutic areas such as autoimmune disorders, infectious diseases, inflammatory disorders, neurological disorders, are also gradually gaining traction. - Although the market was initially led by the large-size pharma players (such as Celgene, Merck, Novartis), the current market is characterized by the presence of several small / mid-sized pharma players. Notable examples of the small and mid-sized firms include 4SC, Chroma Therapeutics, CrystalGenomics, Curis, Evgen Pharma, FORUM Pharmaceuticals, Karus Therapeutics, Mirati Therapeutics, MEI Pharma, Shenzhen Chipscreen Biosciences, Syndax Pharmaceuticals and TetraLogic Pharmaceuticals. - In addition, there are several non-industry institutes and universities that are primarily carrying out preclinical research. Examples of these include Harvard Medical School (BG45), Imperial College London (C1A), Kyoto University (Jd, Sd), National Taiwan University (Quinazolin-4-one derivatives), Taipei Medical University (MPT0E028), University of Messina (MC-1575, MC-1568). - Four of the five approved drugs are pan-HDAC inhibitors targeting HDAC isoforms non-specifically. However, in the past few years, several class selective HDAC inhibitors have entered the clinic; these are associated with a higher efficacy and result in decreased toxicity from the treatment. Of the total HDAC inhibitors identified, 52% of the molecules are class specific; of these, 33% molecules target Class I specific isoforms and the rest target Class II specific isoforms of HDACs. Notable examples of molecules targeting class-specific HDACs includeentinostat (phase III), resminostat (phase II), SHP-141 (phase II), mocetinostat (phase II), CHR-3996 (phase I/II) and ricolinostat (phase I/II). - The HDAC inhibitors market is expected to grow at a healthy annual rate of 32% over the next decade.With multiple potential target indications, Istodax® is expected to capture the largest market share (close to 21%) in 2026, followed by entinostat, Farydak® and Beleodaq®.

Histone deacetylases (HDACs) are widely studied targets for the treatment of cancer and other diseases. Up to now, over twenty HDAC inhibitors have entered clinical studies and two of them have already reached the market, namely the hydroxamic acid derivative SAHA (vorinostat, Zolinza) and the cyclic depsipeptide FK228 (romidepsin, Istodax) that have been approved for the treatment of cutaneous T-cell lymphoma (CTCL). A common aspect of the first HDAC inhibitors is the absence of any particular selectivity towards specific isozymes. Some of molecules resulted to be "pan"-HDAC inhibitors, while others are classa I selective. In the meantime, the knowledge of HDAC biology has continuously progressed. Key advances in the structural biology of various isozymes, reliable molecular homology models as well as suitable biological assays have provided new tools for drug discovery activities. This Minireview aims at surveying these recent developments as well as the design, synthesis and biological characterization of isoform-selective derivatives. © 2014 WILEY-VCH Verlag GmbH and Co.

Two major mechanisms have been causally implicated in the establishment of cellular senescence: the activation of the DNA damage response (DDR) pathway and the formation of senescence-associated heterochromatic foci (SAHF). Here we show that in human fibroblasts resistant to premature p16 INK4a induction, SAHF are preferentially formed following oncogene activation but are not detected during replicative cellular senescence or on exposure to a variety of senescence-inducing stimuli. Oncogene-induced SAHF formation depends on DNA replication and ATR (ataxia telangiectasia and Rad3-related). Inactivation of ATM (ataxia telangiectasia mutated) or p53 allows the proliferation of oncogene-expressing cells that retain increased heterochromatin induction. In human cancers, levels of heterochromatin markers are higher than in normal tissues, and are independent of the proliferative index or stage of the tumours. Pharmacological and genetic perturbation of heterochromatin in oncogene-expressing cells increase DDR signalling and lead to apoptosis. In vivo, a histone deacetylase inhibitor (HDACi) causes heterochromatin relaxation, increased DDR, apoptosis and tumour regression. These results indicate that heterochromatin induced by oncogenic stress restrains DDR and suggest that the use of chromatin-modifying drugs in cancer therapies may benefit from the study of chromatin and DDR status of tumours. © 2011 Macmillan Publishers Limited.

Aberrant histone acetylation was physiopathologically associated with the development of acute myeloid leukemias (AMLs). Reversal of histone deacetylation by histone deacetylase inhibitor (HDACis) activates a cell death program that allows tumor regression in mouse models of AMLs. We have used several models of PML-RARA-driven acute promyelocytic leukemias (APLs) to analyze the in vivo effects of valproic acid, a well-characterized HDACis. Valproic acid (VPA)-induced rapid tumor regression and sharply prolonged survival. However, discontinuation of treatment was associated to an immediate relapse. In vivo, as well as ex vivo, VPA-induced terminal granulocytic differentiation. Yet, despite full differentiation, leukemia-initiating cell (LIC) activity was actually enhanced by VPA treatment. In contrast to all-trans retinoic acid (ATRA) or arsenic, VPA did not degrade PML-RARA. However, in combination with ATRA, VPA synergized for PML-RARA degradation and LIC eradication in vivo. Our studies indicate that VPA triggers differentiation, but spares LIC activity, further uncouple differentiation from APL clearance and stress the importance of PML-RARA degradation in APL cure. © 2012 Macmillan Publishers Limited.

In the last decades, inhibitors of histone deacetylases (HDAC) have become an important class of anti-cancer agents. In a previous study we described the synthesis of spiro[chromane-2,4-piperidine]hydroxamic acid derivatives able to inhibit histone deacetylase enzymes. Herein, we present our exploration for new derivatives by replacing the piperidine moiety with various cycloamines. The goal was to obtain highly potent compounds with a good invitro ADME profile. In addition, molecular modeling studies unravelled the binding mode of these inhibitors.

The pure four diastereomers (11a-d) of trans-benzyl (1-((4-(2-aminocyclopropyl)phenyl)amino)-1-oxo-3-phenylpropan-2-yl)carbamate hydrochloride 11, previously described by us as LSD1 inhibitor, were obtained by enantiospecific synthesis/chiral HPLC separation method. Tested in LSD1 and MAO assays, 11b (S,1S,2R) and 11d (R,1S,2R) were the most potent isomers against LSD1 and were less active against MAO-A and practically inactive against MAO-B. In cells, all the four diastereomers induced Gfi-1b and ITGAM gene expression in NB4 cells, accordingly with their LSD1 inhibition, and 11b and 11d inhibited the colony forming potential in murine promyelocytic blasts.

Hooking up! Hsp90 is a molecular chaperone involved in the stabilisation of numerous client proteins including those involved in oncogenic transformations. Through a high-throughput biochemical fragment screen, we have identified novel fragment inhibitors of Hsp90. Two fragment hits were combined to give a dual-fragment Hsp90 complex, and the following successful fragment-linking resulted in a 1000-fold improvement in activity.
