Synthesis of Pyrazole-Based Inhibitors of the Bacterial Enzyme -Succinyl-l,l-2,6-Diaminopimelic Acid Desuccinylase (DapE) as Potential Antibiotics.

Based on the inhibitory potencies from earlier reported tetrazole thioether analogs, we now describe the synthesis and inhibition of pyrazole-based inhibitors of -succinyl-l,l-2,6-diaminopimelic acid desuccinylase (DapE) from (DapE). The most potent pyrazole analog bears an aminopyridine amide with an IC of 17.9 ± 8.

Dynamics of a single anisotropic particle under various resetting protocols.

We study analytically the dynamics of an anisotropic particle subjected to different stochastic resetting schemes in two dimensions. The Brownian motion of shape-asymmetric particles in two dimensions results in anisotropic diffusion at short times, while the late-time transport is isotropic due to rotational diffusion. We show that the presence of orientational resetting promotes the anisotropy to late times.

Response of a von Hippel-Lindau-associated optic nerve hemangioblastoma to belzutifan.

Purpose: To demonstrate the response of a juxtapapillary retinal hemangioblastoma (JRH) to belzutifan in a patient with Von-Hippel-Lindau syndrome (VHL).

Methods: This case report includes fundus photography and optical coherence tomography to compare a juxtapapillary retinal hemangioblastoma (JRH) before and 24 months after treatment with belzutifan.

Results: An 18-year-old woman with VHL was diagnosed with a juxtapapillary retinal hemangioblastoma (JRH) at age 13.

In vitro and in vivo characterization of Invega Sustenna® (paliperidone palmitate long-acting injectable suspension).

The aim of this study was to comprehensively characterize paliperidone palmitate (PP) long-acting suspension (Invega Sustenna®) through reverse engineering. We developed a series of analytical methods to assess critical quality attributes of four batches of Invega Sustenna®. The size distributions of the four batches of suspensions were measured using laser diffraction, and variations in the D50 and D90 parameters were observed.
