Abstract
There is an urgent need for antivirals targeting the SARS-CoV-2 virus to fight the current COVID-19 pandemic. The SARS-CoV-2 main protease (3CLpro) represents a promising target for antiviral therapy. The lack of selectivity for some of the reported 3CLpro inhibitors, specifically versus cathepsin L, raises potential safety and efficacy concerns. ALG-097111 potently inhibited SARS-CoV-2 3CLpro (IC50 = 7 nM) without affecting the activity of human cathepsin L (IC50 > 10 μM). When ALG-097111 was dosed in hamsters challenged with SARS-CoV-2, a robust and significant 3.5 log10 (RNA copies/mg) reduction of the viral RNA copies and 3.7 log10 (TCID50/mg) reduction in the infectious virus titers in the lungs was observed. These results provide the first in vivo validation for the SARS-CoV-2 3CLpro as a promising therapeutic target for selective small molecule inhibitors.

Abstract
Nav1.7 is an extensively investigated target for pain with a strong genetic link in humans, yet in spite of this effort, it remains challenging to identify efficacious, selective, and safe inhibitors. Here, we disclose the discovery and preclinical profile of GDC-0276 (1) and GDC-0310 (2), selective Nav1.7 inhibitors that have completed Phase 1 trials. Our initial search focused on close-in analogues to early compound 3. This resulted in the discovery of GDC-0276 (1), which possessed improved metabolic stability and an acceptable overall pharmacokinetics profile. To further derisk the predicted human pharmacokinetics and enable QD dosing, additional optimization of the scaffold was conducted, resulting in the discovery of a novel series of N-benzyl piperidine Nav1.7 inhibitors. Improvement of the metabolic stability by blocking the labile benzylic position led to the discovery of GDC-0310 (2), which possesses improved Nav selectivity and pharmacokinetic profile over 1.

Abstract
Abstract
Protein arginine methyltransferase-5 (PRMT5) regulates many essential biological processes by catalyzing the symmetric di-methylation of arginine (sDMA) on a variety of histones and non-histone proteins. PRMT5 activity is dysregulated across many hematological and solid tumor and its overexpression is associated with poor patient prognosis. PRMT5 is also often overexpressed in cancer cells. Genetic and pharmacological inactivation have confirmed the importance of PRMT5 activity to the survival of many cancer cells, including hepatocellular carcinoma (HCC) and non-small cell lung cancer (NSCLC). Thus, inhibiting PRTMT5 activity has emerged as an attractive therapeutic strategy in oncology.
We used structure-based drug design to identify novel small molecule inhibitors of PRMT5. ALG-070005, ALG-070043 and ALG-070017 inhibited PRMT5 enzymatic activity in biochemical assays with half-maximal inhibitory concentrations (IC50s) values between 50-150 pM and showed high selectivity against a panel of six other PRMTs. In HepG2 cells (HCC), ALG-070005, ALG-070043 and ALG-070017 potently decreased sDMA levels and inhibited cell proliferation with IC50 values of 1, 3, and 0.2 nM, respectively. These compounds also exhibited similar antiproliferative activity in A549 NSCLC cells. The three novel PRMT5 inhibitors demonstrated favorable ADME/PK profiles with exposure levels in target organs well above IC50 values, even 24 hours after dosing. When dosed orally in mice, these Aligos compounds inhibited tumor growth in HCC and NSCLC xenograft models, with concomitant inhibition of sDMA in the tumor.
In conclusion, we identified and characterized novel potent and selective inhibitors of PRMT5 with antiproliferative effects in various preclinical models of HCC and lung cancers. These drug candidates also have a broad therapeutic potential in oncology beyond HCC and lung cancer.

Abstract
Abstract
Introduction: The STING (STimulator of INterferon Genes) protein has been identified as an attractive target for cancer immunotherapy due to its central role in inducing T-cell mediated tumor control. Here we describe the preclinical characteristics of the novel STING agonist, ALG-031048, that demonstrates potent anti-tumoral activity in in vivo mouse models.
Methods: Binding to STING was determined using differential scanning fluorimetry (DSF). Cellular activation and cytokine release were assessed using HEK 293T reporter cell lines as well as THP-1 and Raw264.7 cells. In vitro stability was measured in the presence of snake venom phosphodiesterase (SVPD). In vivo anti-tumoral activity was tested in the syngeneic CT26 and B16F10 mouse model.
Results: ALG-031048 demonstrated potent binding to the STING R232 protein in the DSF assay with a mean Kd of 3.12 ± 0.12 μM and a thermal shift of 12.8 °C, similar to the natural ligand 2'3'cGAMP (Kd of 2.75 ± 0.78 μM, shift of 16.7°C) or the clinical stage STING agonist, ADU-S100 (Kd of 4.61 ± 0.42 μM, shift of 10.7°C). In the HEK 293T R232 reporter assay, ALG-031048 was more potent than ADU-S100 with a mean EC50 of 55.9 ± 24.1 and 30.3 ± 17.1 nM for the IFNβ and IRF reporter, respectively, compared to ADU-S100 with EC50 values of 233 ± 179 and 88.7 ± 35.6 nM. Cellular activation was confirmed in THP-1 and Raw264.7 cells where ALG-031048 induced the secretion of IFNβ and CXCL-10. ALG-031048 was highly stable and exhibited no degradation for up to 24 hours in the presence of SVPD while ADU-S100 and 2'3'cGAMP were quickly degraded with less than 10% remaining after 24 hours. In vivo, 3 intra-tumoral (IT) doses of 100 μg ALG-031048 q3d caused complete tumor regression in 90% of animals in the CT26 mouse colon carcinoma model, while treatment with 25 μg ALG-031048 IT 3xq3d resulted in survival of 60 % of animals. In contrast, only 10 and 44% of mice showed complete tumor regression when treated IT 3xq3d with 25 or 100 μg ADU-S100, respectively. To study whether induction of a protective immune response was associated with STING agonist treatment, surviving animals were re-challenged with a second inoculation of CT26 cells on the contra-lateral side. All naïve animals formed tumors within 23-30 days. In contrast, 5 out of 5 and 8 out of 9 mice pre-treated with 25 or 100 μg ALG-031048, respectively, did not exhibit any significant tumor growth over 40 days, while 3 out of 4 animals pretreated with 100 μg ADU-S100 showed complete tumor suppression. Initial results using the B16F10 mouse melanoma model confirmed the potent anti-tumoral activity of ALG-031048 observed in the CT26 model.
Summary: ALG-031048 is a novel STING agonist combining high stability and excellent in vitro potency. In preclinical models, ALG-031048 demonstrated potent and long-lasting tumor suppression. ALG-031048 is advancing in toxicology studies for further profiling as a clinical candidate.

Abstract
Bruton's tyrosine kinase (Btk) is thought to play a pathogenic role in chronic immune diseases such as rheumatoid arthritis and lupus. While covalent, irreversible Btk inhibitors are approved for treatment of hematologic malignancies, they are not approved for autoimmune indications. In efforts to develop additional series of reversible Btk inhibitors for chronic immune diseases, we sought to differentiate from our clinical stage inhibitor fenebrutinib using cyclopropyl amide isosteres of the 2-aminopyridyl group to occupy the flat, lipophilic H2 pocket. While drug-like properties were retained-and in some cases improved-a safety liability in the form of hERG inhibition was observed. When a fluorocyclopropyl amide was incorporated, Btk and off-target activity was found to be stereodependent and a lead compound was identified in the form of the (R,R)- stereoisomer.

Abstract
Colony-stimulating factor 1 (CSF1) and interleukin 34 (IL34) signal via the CSF1 receptor to regulate macrophage differentiation. Studies in IL34- or CSF1-deficient mice have revealed that IL34 function is limited to the central nervous system and skin during development. However, the roles of IL34 and CSF1 at homeostasis or in the context of inflammatory diseases or cancer in wild-type mice have not been clarified in vivo. By neutralizing CSF1 and/or IL34 in adult mice, we identified that they play important roles in macrophage differentiation, specifically in steady-state microglia, Langerhans cells, and kidney macrophages. In several inflammatory models, neutralization of both CSF1 and IL34 contributed to maximal disease protection. However, in a myeloid cell-rich tumor model, CSF1 but not IL34 was required for tumor-associated macrophage accumulation and immune homeostasis. Analysis of human inflammatory conditions reveals IL34 upregulation that may account for the protection requirement of IL34 blockade. Furthermore, evaluation of IL34 and CSF1 blockade treatment during Listeria infection reveals no substantial safety concerns. Thus, IL34 and CSF1 play non-redundant roles in macrophage differentiation, and therapeutic intervention targeting IL34 and/or CSF1 may provide an effective treatment in macrophage-driven immune-pathologies.

Abstract
Both preclinical evidence and clinical evidence suggest that α7 nicotinic acetylcholine receptor activation (α7nAChR) improves cognitive function, the decline of which is associated with conditions such as Alzheimer's disease and schizophrenia. Moreover, allosteric modulation of α7nAChR is an emerging therapeutic strategy in an attempt to avoid the rapid desensitization properties associated with the α7nAChR after orthosteric activation. We used a calcium assay to screen for positive allosteric modulators (PAMs) of α7nAChR and report on the pharmacologic characterization of the novel compound RO5126946 (5-chloro-N-[(1S,3R)-2,2-dimethyl-3-(4-sulfamoyl-phenyl)-cyclopropyl]-2-methoxy-benzamide), which allosterically modulates α7nAChR activity. RO5126946 increased acetylcholine-evoked peak current and delayed current decay but did not affect the recovery of α7nAChRs from desensitization. In addition, RO5126946's effects were absent when nicotine-evoked currents were completely blocked by coapplication of the α7nAChR-selective antagonist methyl-lycaconitine. RO5126946 enhanced α7nAChR synaptic transmission and positively modulated GABAergic responses. The absence of RO5126946 effects at human α4β2nAChR and 5-hydroxytryptamine 3 receptors, among others, indicated selectivity for α7nAChRs. In vivo, RO5126946 is orally bioavailable and brain-penetrant and improves associative learning in a scopolamine-induced deficit model of fear conditioning in rats. In addition, procognitive effects of RO5126946 were investigated in the presence of nicotine to address potential pharmacologic interactions on behavior. RO5126946 potentiated nicotine's effects on fear memory when both compounds were administered at subthreshold doses and did not interfere with procognitive effects observed when both compounds were administered at effective doses. Overall, RO5126946 is a novel α7nAChR PAM with cognitive-enhancing properties.

Abstract
BACKGROUND Changes in synaptic efficacy are believed to mediate the processes of learning and memory formation. Accumulating evidence implicates cell adhesion molecules in activity-dependent synaptic modifications associated with long-term potentiation (LTP); however, there is no precedence for the selective role of this molecule class in long-term depression (LTD). The mechanisms that modulate these processes still remain unclear. RESULTS We report a novel role for glycosylphosphatidyl inositol (GPI)-anchored contactin in hippocampal CA1 synaptic plasticity. Contactin selectively supports paired-pulse facilitation (PPF) and NMDA (N-methyl-D-aspartate) receptor-dependent LTD but is not required for synaptic morphology, basal transmission, or LTP. Molecular analyses indicate that contactin is essential for the membrane and synaptic targeting of the contactin-associated protein (Caspr/paranodin) and for the proper distribution of a presumptive ligand, receptor protein tyrosine phosphatase beta (RPTPbeta)/phosphacan. CONCLUSIONS These results indicate that contactin plays a selective role in synaptic plasticity and identify PPF and LTD, but not LTP, as contactin-dependent processes. Engagement of the contactin-Caspr complex with RPTPbeta may thus regulate cell-cell interactions contributing to specific synaptic plasticity forms.

Abstract
Hippocampal long-term potentiation (LTP) and long-term depression (LTD) are the most widely studied forms of synaptic plasticity thought to underlie spatial learning and memory. We report here that RARbeta deficiency in mice virtually eliminates hippocampal CA1 LTP and LTD. It also results in substantial performance deficits in spatial learning and memory tasks. Surprisingly, RXRgamma null mice exhibit a distinct phenotype in which LTD is lost whereas LTP is normal. Thus, while retinoid receptors contribute to both LTP and LTD, they do so in different ways. These findings not only genetically uncouple LTP and LTD but also reveal a novel and unexpected role for vitamin A in higher cognitive functions.
