Cryptococcus Meningoencephalitis With Severe Localizing Neurological Deficits Mimicking a Large Right Middle Cerebral Artery Infarct in a HIV Patient.

Immunocompromised patients with Cryptococcal meningoencephalitis can develop focal neurological signs and symptoms. Stroke and abscess are usually the leading etiologies. Definitively localized non-fluctuating deficits mimicking a large middle cerebral artery (MCA) infarct without corresponding MRI findings is rare.

Second generation 2-aminoimidazole based advanced glycation end product inhibitors and breakers.

The formation of advanced glycation end-products (AGE) as a result of the action of reducing sugars on host macromolecules plays a role in increased morbidity of diabetic patients. There are currently no clinically available therapeutics for the prevention or eradication of AGEs. Following our previous identification of 2-aminoimidazole (2-AI) based AGE inhibitors and breakers, we now report the use of a rapid, scalable, two-step procedure to access a second generation of 2-AI based anti-AGE compounds from commercially available amino acids.

Inhibition and breaking of advanced glycation end-products (AGEs) with bis-2-aminoimidazole derivatives.

Advanced glycation end-products (AGEs), unregulated modifications to host macromolecules that occur as a result of metabolic dysregulation, play a role in many diabetes related complications, inflammation and aging, and may lead to increased cardiovascular risk. Small molecules that have the ability to inhibit AGE formation, and even break preformed AGEs have enormous therapeutic potential in the treatment of these disease states. We report the screening of a series of 2-aminoimidazloles for anti-AGE activity, and the identification of a bis-2-aminoimidazole lead compound that possesses superior AGE inhibition and breaking activity compared to the known AGE inhibitor aminoguanidine.
