Using structure based drug design, a novel class of potent coagulation factor IXa (FIXa) inhibitors was designed and synthesized. High selectivity over FXa inhibition was achieved. Selected compounds were evaluated in rat IV/PO pharmacokinetic (PK) studies and demonstrated desirable oral PK profiles. Finally, the pharmacodynamics (PD) of this class of molecules were evaluated in thrombin generation assay (TGA) in Corn Trypsin Inhibitor (CTI) citrated human plasma and demonstrated characteristics of a FIXa inhibitor.

Parasitic diseases continue to be a major public health burden, particularly in low- and middle-income countries. With the emergence of drug-resistant strains and limitations of current therapies, there is a growing interest in natural products as alternative treatment options. Coumarins, a diverse class of plant-derived secondary metabolites, have shown significant potential as antiparasitic agents.

is a protozoan parasite that typically causes self-limited diarrhea in healthy individuals but can result in prolonged, severe illness in those who are immunocompromised. While this infection is well recognized in HIV-positive patients, it is less frequently reported in individuals with lupus nephritis on immunosuppressive therapy. We report the case of a 27-year-old man with biopsy-confirmed class IV lupus nephritis who was receiving cyclophosphamide and corticosteroids.

Antibody-drug conjugates (ADCs) represent a transformative class of cancer therapies that combine the specificity of monoclonal antibodies with the cytotoxicity of potent drug payloads. This study presents the development and evaluation of a novel linker platform designed to enhance ADC stability and pharmacokinetics by addressing the limitations associated with traditional cleavable linkers. Using trastuzumab conjugated with a payload linker consisting of this platform and exo-EVC-Exatecan (APL-1082), we examined key parameters, including efficacy and pharmacokinetic profiles in rat models, to directly compare it with the clinically validated trastuzumab-deruxtecan (T-DXd, Enhertu).

Unlabelled: The rise of β-lactamase-mediated resistance in Gram-negative pathogens has created an urgent need for novel inhibitors to preserve antibiotic efficacy. This study explores the potential of curcumin, a natural polyphenol with known antimicrobial properties, as a broad-spectrum inhibitor of class A serine-β-lactamases (SBLs) through comprehensive computational analysis. Using molecular docking, 200 ns molecular dynamics simulations, and binding energy calculations, we investigated curcumin's interactions with three clinically important SBLs: KPC-3, CTX-M-15, and L2.

Background: Imeglimin (Ime), the first in a novel class of antidiabetic agents, has potential therapeutic effects on diabetic peripheral neuropathy (DPN). This study aimed to evaluate and compare the effects on cellular metabolic function and reactive oxygen species (ROS) levels in high glucose-treated mouse Schwann cells (SCs), an DPN model, with those of metformin (Met), a conventional antidiabetic agent known for its beneficial effects on DPN. The roles of PPARα and fatty acid-binding proteins 5 and 7 (FABP5 and FABP7), both of which have been implicated in the pathogenesis of DPN, were also investigated.
