Abstract
Twenty-nine fluorinated corroles were prepared, spectroscopically characterized, and studied for their antiviral activity against human cytomegalovirus infection. Six corroles were also fully characterized by X-ray crystallography giving insights on their geometrical features. The halogenated corroles reported herein exhibit significantly improved antiviral activity over their non-halogenated counterparts and over nitro-corrole analogs previously reported. Full activity of thirteen A3-corroles is achieved with four fluorine atoms present on the meso-phenyl ring reaching a selectivity index above 300. The maximum activity is achieved for A2B-corroles with selectivity indexes above 400. We thus demonstrate that the fluorocorrole is a highly potent platform to synthesize a new generation of anti hCMV molecules.

Abstract
Human cytomegalovirus (hCMV) is responsible for several pathologies impacting immunocompromised patients and can trigger life-threatening infection. Several antivirals are available and are used in the clinic, but hCMV resistant strains have appeared and patients have encountered therapeutic failure. Hence, there is a constant need for new best in class or first in class antiviral molecules. We have previously shown that nitrocorroles could be used as a potent anti-hCMV agent without acute toxicity in mice. They therefore represent an excellent platform to perform structure-activity relationship (SAR) studies and to increase efficiency or reduce toxicity. We have generated original A2B- and A3-substituted nitrocorroles and have discovered optimized compounds with selectivity indices above 200. These compounds are easily synthesized in only one to two-step reactions; they are up-scalable and cost efficient. They are therefore excellent candidates for hCMV therapies and they pave the way for a new generation of molecules.

Abstract
Meningo-encephalitis is a set of threatening diseases. The treatment needs to be started quickly for pathogens such as herpes simplex virus type 1 or Listeria monocytogenes. Apart from these classical etiologies, many other diseases may induce meningo-encephalitis. We report the case of a patient, infected with HIV, who presented a history of meningo-encephalitis due to herpes simplex type 1. Three weeks later, he presented an encephalopathy due to aciclovir and then we discovered a chronic meningitis in relation with his HIV infection.
