Selective HDAC6 Inhibitors for Cancer and Neurodegenerative Disease

HDAC6 plays an important role in neurological, inflammatory, and other diseases; and thus is an important target for therapeutic intervention.  To date, there are no FDA-approved HDAC6-targeting drugs and most pipeline candidates suffer from poor target engagement, inadequate brain penetration, and low tolerability. There are five HDAC6 clinical candidates for the treatment of mostly non-CNS cancers as their pharmacokinetic liabilities exclude them from targeting HDAC6-implicated neurological diseases, urging for the development to address these challenges. They also demonstrate off-target toxicity due to limited selectivity, leading to adverse effects in patients. Selective inhibitors have thus been the focus of development over the past decade, though no selective and potent HDAC6 inhibitor has yet been approved to date.

Appetite-Suppressing Cytokinin for Weight Loss and Obesity Treatment

Obesity has increased to pandemic levels and is associated with an increased risk of metabolic diseases, including type 2 diabetes mellitus (T2DM), cardiovascular disease and cancer.  While the most effective means to reduce weight is healthy eating and exercise, adherence to these recommendations are a challenge, especially in individuals with a high body weight or BMI >30.  Alternatives to these solutions include anti-obesity therapeutics and supplements. Limited therapeutic options are approved by the FDA, such as Glp-1R agonists, but they are restricted to high BMI patients, are costly for insurers/individuals, have limited efficacy or have unpleasant side effects. Similarly, several supplements are available, but none are regarded as being efficacious unless combined with diet and exercise.  Consequently, an unmet need in effective weight loss management exists especially for those individuals in the BMI range of 25 – 32 who want to lose a few pounds to avoid the progression towards metabolic disease without altering their current lifestyle.

Novel Nematicides for Animal Health and Plant Applications

Parasitic nematodes are a major problem in agriculture where their infection of livestock and parasitization of plants are a threat to food security and result in billions of dollars of lost productivity.  Several classes of nematicides, compounds that are toxic to nematodes, have been approved and successfully integrated into the food generation process.  However, two problems with current nematicides are increasing resistance to their effects and serious concerns with their environmental impact, the latter of which has led to withdrawal of commercially successful nematicides from general use. Researchers at the University of Toronto have discovered two small molecule scaffolds for potential use as nematicides in agricultural applications.

Peptide Therapeutic for Parkinson’s Disease

BACKGROUND

Parkinson’s disease is a disabling and progressive neurological disorder characterized by degeneration of dopamine-producing neurons. Current therapies to replace dopamine are only symptomatic and are associated with considerable complications as the disease progresses. No disease-modifying therapies that slow or stop disease progression are available or likely to emerge soon. With Parkinson’s disease affecting over 6 million people worldwide and being the fastest growing neurological disease, this is a huge unmet need in neurodegeneration.

Immunotyping COVID-19 Patients Using Novel Protein Complementation-Based Assay

To date, pathogenic examination of SARS-CoV-2 virus RNA using RT-PCR is considered the gold standard method for diagnosis. However, this test is accompanied with high false negative rate mainly due to the difficulty of sampling. In addition, application of this test to screen suspected patients is currently limited by the lack of sufficient supply of experimental reagents, facilities and well-trained operators in many countries. Serological test of antibodies (Abs) against SARS-CoV-2 virus in patients is a complementary approach.

Inhibition of PKN1 As Therapy For Chronic Lymphocytic Leukemia (CLL)

Our researchers have developed a new strategy to overcome the drug resistance often faced during the treatment of CLL by inhibiting the TNFR family signalling through inhibition of a kinase, PKN1, which is involved in TRAF1 regulation. TRAF1 is overexpressed in 48% of B cell related cancers with highest expression in mature B cell lymphomas and the most refractory B-CLL. Thus targeting TRAF1 in human CLL has the potential to improve the disease outcome. Non-coding single nucleotide polymorphisms in TRAF1 have also been linked to non-Hodgkin’s lymphoma.

UBA5 Inhibitors for the Treatment of Cancer and Leishmaniasis

Cancer cells produce and break down proteins more rapidly than normal cells, and are more sensitive to changes in the regulation of processes involving proteins. The ubiquitin-proteasome system (UPS) is the main protein process that governs protein recycling in cells, and is overactive in many cancers such as leukemia and multiple myeloma. The proteasome is a large protein analogous to the recycling plant of the cell, and inhibition of the UPS with proteasome inhibitors, such as Velcade (bortezomib), results in effective cancer cell death due to the accumulation of undigested proteins.

Methods for the Prevention and Treatment of Memory Impairment

Over 234 million surgical operations are performed worldwide each year. General anesthetics have dramatically reduced human suffering, but the mechanisms of action of these drugs remain poorly understood. The hippocampus (memory centre in the brain) shelters a population of inhibitory receptors that underlie the memory-blocking properties. GABA (i.e., g-aminobutyric acid) receptors are the most abundant and widely distributed within the central nervous system of mammals. Therefore, these receptors play pivotal roles in virtually all brain functions including memory.
