Synthesis of cannabidiol-based compounds as ACE2 inhibitors with potential application in the treatment of COVID-19.

Cannabis is a general name for plants of the genus Cannabis. Used as fiber, medicine, drug, for religious, therapeutic, and hedonistic purposes along the millenia, it is mostly known for its psychoactive properties. One of its major constituents, cannabidiol (CBD), a non-psychoactive substance, among many other biological activities, has shown potential as an anti-SARS-CoV-2 drug.

Benzo[]indole-4,9-dione Derivatives Effectively Inhibit the Growth of Triple-Negative Breast Cancer.

Triple-negative breast cancer (TNBC) is a subtype of breast cancer with poor clinical outcome, and currently no effective targeted therapies are available. Indole compounds have been shown to have potential antitumor activity against various cancer cells. In the present study, we found that new four benzo[]indole-4,9-dione derivatives reduce TNBC cell viability by reactive oxygen species (ROS) accumulation stress in vitro.

Novel Single Inhibitor of HDAC6/8 and Dual Inhibitor of PI3K/HDAC6 as Potential Alternative Treatments for Prostate Cancer.

Background: Prostate cancer is the second most frequently diagnosed malignancy worldwide. Here, the cytotoxic and antimetastatic effects of a new HDAC6/8 inhibitor, LASSBio-1911, and a new dual-PI3K/HDAC6 inhibitor, LASSBio-2208, were evaluated against PC3 prostate cancer cell line.

Methods: A MTT assay was used to assess the cell viability.

Design, Synthesis, and Pharmacological Evaluation of First-in-Class Multitarget N-Acylhydrazone Derivatives as Selective HDAC6/8 and PI3Kα Inhibitors.

Targeting histone deacetylases (HDACs) and phosphatidylinositol 3-kinases (PI3Ks) is a very promising approach for cancer treatment. This manuscript describes the design, synthesis, in vitro pharmacological profile, and molecular modeling of a novel class of N-acylhydrazone (NAH) derivatives that act as HDAC6/8 and PI3Kα dual inhibitors. The surprising selectivity for PI3Kα may be related to differences in the conformation in the active site.

Synthesis and pharmacological evaluation of novel isoquinoline N-sulphonylhydrazones designed as ROCK inhibitors.

In this study, we synthesized a new congener series of N-sulphonylhydrazones designed as candidate ROCK inhibitors using the molecular hybridization of the clinically approved drug fasudil (1) and the IKK-β inhibitor LASSBio-1524 (2). Among the synthesized compounds, the N-methylated derivative 11 (LASSBio-2065) showed the best inhibitory profile for both ROCK isoforms, with IC values of 3.1 and 3.

ROCK inhibition with Fasudil induces beta-catenin nuclear translocation and inhibits cell migration of MDA-MB 231 human breast cancer cells.

Tumor aggressiveness is usually associated with metastasis. MDA-MB 231, a triple-negative breast cancer (TNBC), is an aggressive type of breast cancer and associated with early metastasis. The Rho/ROCK pathway is a key regulator of cell motility involving cytoskeleton regulation through stabilization of actin filaments and stress fiber formation.

Histochemistry and Immunohistochemistry Evaluation of the Abrikossoff's Tumour of the Tongue: a Case Report.

Abrikossoff's tumour is a rare benign soft tissue neoplasm that can occur in any part of the body, including the orofacial region. The tumour is usually benign, but there are reports of cases in which the tumour shows a locally aggressive behaviour, malignancy, and distant metastases. The aetiology is unknown, since several studies have shown that different cells are involved.

Characterization of the inflammatory response during Ehrlich ascitic tumor development.

Introduction: Ehrlich tumor is a mammary adenocarcinoma with aggressive behavior. Inoculated in mice peritoneal cavity, the Ehrlich tumor grows in ascitic form (EAT). Since inflammation modulates tumor progression we further investigated the inflammatory response during EAT growth.
