Abstract
The paracaspase MALT1 has emerged as a key regulator of immune signaling, which also promotes tumor development by both cancer cell-intrinsic and -extrinsic mechanisms. As an integral subunit of the CARD11-BCL10-MALT1 (CBM) signaling complex, MALT1 has an intriguing dual function in lymphocytes. MALT1 acts as a scaffolding protein to drive activation of NF-κB transcription factors and as a protease to modulate signaling and immune activation by cleavage of distinct substrates. Aberrant MALT1 activity is critical for NF-κB-dependent survival and proliferation of malignant cancer cells, which is fostered by paracaspase-catalyzed inactivation of negative regulators of the canonical NF-κB pathway like A20, CYLD and RelB. Specifically, B cell receptor-addicted lymphomas rely strongly on this cancer cell-intrinsic MALT1 protease function, but also survival, proliferation and metastasis of certain solid cancers is sensitive to MALT1 inhibition. Beyond this, MALT1 protease exercises a cancer cell-extrinsic role by maintaining the immune-suppressive function of regulatory T (Treg) cells in the tumor microenvironment (TME). MALT1 inhibition is able to convert immune-suppressive to pro-inflammatory Treg cells in the TME of solid cancers, thereby eliciting a robust anti-tumor immunity that can augment the effects of checkpoint inhibitors. Therefore, the cancer cell-intrinsic and -extrinsic tumor promoting MALT1 protease functions offer unique therapeutic opportunities, which has motivated the development of potent and selective MALT1 inhibitors currently under pre-clinical and clinical evaluation.

Abstract
Inhibition of mucosa-associated lymphoid tissue lymphoma translocation protein-1 (MALT1) is a promising strategy to modulate NF-κB signaling, with the potential to treat B-cell lymphoma and autoimmune diseases. We describe the discovery and optimization of (1s,4s)-N,N'-diaryl cyclohexane-1,4-diamines, a novel series of allosteric MALT1 inhibitors, resulting in compound 8 with single digit micromolar cell potency. X-ray analysis confirms that this compound binds to an induced allosteric site in MALT1. Compound 8 is highly selective and has an excellent in vivo rat PK profile with low clearance and high oral bioavailability, making it a promising lead for further optimization.

Abstract
INTRODUCTION MALT1 is the only human paracaspase, a protease with unique cleavage activity and substrate specificity. As a key regulator of immune responses, MALT1 has attracted attention as an immune modulatory target for the treatment of autoimmune/inflammatory diseases. Further, chronic MALT1 protease activation drives survival of lymphomas, suggesting that MALT1 is a suitable drug target for lymphoid malignancies. Recent studies have indicated that MALT1 inhibition impairs immune suppressive function of regulatory T cells in the tumor microenvironment, suggesting that MALT1 inhibitors may boost anti-tumor immunity in the treatment of solid cancers. AREAS COVERED This review summarizes the literature on MALT1 patents and applications. We discuss the potential therapeutic uses for MALT1 inhibitors based on patents and scientific literature. EXPERT OPINION There has been a steep increase in MALT1 inhibitor patents. Compounds with high selectivity and good bioavailability have been developed. An allosteric binding pocket is the preferred site for potent and selective MALT1 targeting. MALT1 inhibitors have moved to early clinical trials, but toxicological studies indicate that long-term MALT1 inhibition can disrupt immune homeostasis and lead to autoimmunity. Even though this poses risks, preventing immune suppression may favor the use of MALT1 inhibitors in cancer immunotherapies.

Abstract
Marginal zone lymphoma (MZL) represents a group of three distinct though overlapping lymphoid malignancies that includes extranodal, nodal and splenic marginal lymphoma. MZL patients usually present an indolent clinical course, although the disease remains largely incurable, save early stage disease that might be irradiated. Therapeutic advances have been limited due to the small patient population, and have largely been adapted from other indolent lymphomas. Here, we discuss the numerous targets and pathways which may offer the prospect of directly inhibiting the mechanisms identified promoting and sustaining marginal zone lymphomagenesis. In particular, we focus on the agents that may have at least a theoretical application in the disease. Various dysregulated pathways converge to produce an overarching stimulation of nuclear factor κB (NF-κB) and the MYD88-IRAK4 axis, which can be thus leveraged or targeting B-cell receptor signaling through BTK inhibitors (such as ibrutinib, zanubrutinib, acalabrutinib) and PI3K inhibitors (such as idelalisib, copanlisib, duvelisib umbralisib) or via more novel agents in development such as MALT1 inhibitors, SMAC mimetics, NIK inhibitors, IRAK4 or MYD88 inhibitors. NOTCH signaling is also crucial for marginal zone cells, but no clinical data are available with NOTCH inhibitors such as the γ-secretase inhibitor PF-03084014 or the NICD inhibitor CB-103. The hypermethylation phenotype, the overexpression of the PRC2-complex or the presence of TET2 mutations reported in MZL subsets make epigenetic agents (demethylating agents, EZH2 inhibitors, HDAC inhibitors) also potential therapeutic tools for MZL patients.

Abstract
Genetic disruption or short-term pharmacological inhibition of MALT1 protease is effective in several preclinical models of autoimmunity and B cell malignancies. Despite these protective effects, the severe reduction in regulatory T cells (Tregs) and the associated IPEX-like pathology occurring upon congenital disruption of the MALT1 protease in mice has raised concerns about the long-term safety of MALT1 inhibition. Here we describe the results of a series of toxicology studies in rat and dog species using MLT-943, a novel potent and selective MALT1 protease inhibitor. While MLT-943 effectively prevented T cell-dependent B cell immune responses and reduced joint inflammation in the collagen-induced arthritis rat pharmacology model, in both preclinical species, pharmacological inhibition of MALT1 was associated with a rapid and dose-dependent reduction in Tregs and resulted in the progressive appearance of immune abnormalities and clinical signs of an IPEX-like pathology. At the 13-week time point, rats displayed severe intestinal inflammation associated with mast cell activation, high serum IgE levels, systemic T cell activation and mononuclear cell infiltration in multiple tissues. Importantly, using thymectomized rats we demonstrated that MALT1 protease inhibition affects peripheral Treg frequency independently of effects on thymic Treg output and development. Our data confirm the therapeutic potential of MALT1 protease inhibitors but highlight the safety risks and challenges to consider before potential application of such inhibitors into the clinic.

Abstract
Mucosa-associated lymphoid tissue lymphoma translocation protein 1 (MALT1), which plays a crucial role in the nuclear factor-kappa B (NF-κB) activation signaling pathway as a paracaspase, is a new target for immunomodulatory and antitumor drugs. Here, novel inhibitors that target MALT1 allosteric sites were identified by virtual screening FDA-approved drug databases. Paliperidone, a compound that binds to the allosteric site of MALT1, is investigated. An in vitro study found that the proteolytic activity of MALT1 substrate cleavage was blocked by paliperidone. Meanwhile, the MALT1 proteolytic activity was reversible, as demonstrated by the partial recovery of the MALT1 substrate cleavage following compound wash out. The docking analysis of the interaction of MALT1 and paliperidone suggested that two hydrogen bonds formed in the allosteric pocket of MALT1. MALT1 and paliperidone achieved a good equilibrium, as demonstrated by 100 ns molecular dynamic (MD) simulations conducted with the program Gromacs. However, the catalytically active site of the MALT1 complex with paliperidone remained in an inactive conformation. Thus, paliperidone, a noncompetitive and allosteric inhibitor, was screened through in silico and in vitro methods. This study will be of significance for the development of effective and selective drugs that can treat MALT1-driven cancer or autoimmune diseases. Paliperidone was screened as an effective and selective drug that can treat MALT1-driven cancer or autoimmune diseases.![]()
