SAR analysis of a series of acylthiourea derivatives possessing broad-spectrum antiviral activity
摘要:
A series of acylthiourea derivatives were designed, synthesized, and evaluated for broad-spectrum antiviral activity with selected viruses from Poxviridae (vaccinia virus) and two different genera of the family Bunyaviridae (Rift Valley fever and La Crosse viruses). A compound selected from a library screen, compound 1, displayed submicromolar antiviral activity against both vaccinia virus (EC50 = 0.25 mu M) and La Crosse virus (EC50 = 0.27 mu M) in cytopathic effect (CPE) assays. SAR analysis was performed to further improve antiviral potency and to optimize drug-like properties of the initial hits. During our analysis, we identified 26, which was found to be nearly fourfold more potent than 1 against both vaccinia and La Crosse viruses. Selected compounds were further tested to more fully characterize the spectrum of antiviral activity. Many of these possessed single digit micromolar and sub-micromolar antiviral activity against a diverse array of targets, including influenza virus (Orthomyxoviridae), Tacaribe virus (Arenaviridae), and dengue virus (Flaviviridae).

The invention relates to novel hetaryl-phenylenediamine-pyrimidines and to their structurally related oxygen and sulphur analogues of the general formula I, processes for their preparation, and their use as medicaments.
Formal propagation of (hetero)arylamine is achieved via a one-pot Buchwald–Hartwig C–N cross-coupling and nitro reduction sequence, enabling a rapid modular synthesis of diverse amino-di(hetero)arylamines from (hetero)arylamines and halogenated nitrobenzenes. Various functionalized aromatic amines with different electronic and steric environments can be efficiently prolongated to formally incorporate

The present disclosure relates to a novel family of N-heteroaryl secondary para-phenylenediamines, to their preparation, to their use for dyeing the hair and to a dye composition for dyeing keratin fibers, for example, human keratin fibers such as the hair, comprising, in a suitable dyeing medium, at least one heteroaryl secondary para-phenylenediamine. The disclosure also relates to the process using this composition, to its use and to the multi-compartment device and dyeing “kit”.
