Drug repositioning identifies histone deacetylase inhibitors that promote innate immunity in non-tuberculous mycobacterial infection.

Non-tuberculosis infections in immunocompromised patients represent a cause for concern, given the increased risks of infection, and limited treatments available. Herein, we report that molecules for binding to the catalytic site of histone deacetylase (HDAC) inhibit its activity, thus increasing the innate immune response against environmental mycobacteria. The action of HDAC inhibitors (iHDACs) was explored in a model of type II pneumocytes and macrophages infection by .

Longevity of preserved L. seeds: physicochemical characteristics.

Unlabelled: Ex situ conservation of plant biodiversity has been increasingly used to prevent further loss of genetic resources. Seed banks, for example, shelter the passport data of germplasm, preserved in detail, and made available for easy access, actions included in the FAO's Second Global Plan. We examined the deterioration of tomato seeds of different varieties stored for 10-year intervals at COMAV's genebank.

Avocado seeds ( cv. Criollo sp.): Lipophilic compounds profile and biological activities.

This study aimed to evaluate the volatile or lipophilic chemical profiling and the biological activities of avocado ( cv Criollo sp.) seed extracts. Chemical profile of volatile compounds (GC/MS), antioxidant properties (phenolic compounds, DPPH radical scavenging activities and reducing power), and antimicrobial activity ( Typhimurium and ) of avocado ( cv Criollo sp.

Biguanides: Species with versatile therapeutic applications.

Biguanides are compounds in which two guanidine moieties are fused to form a highly conjugated system. Biguanides are highly basic and hence they are available as salts mostly hydrochloride salts, these cationic species have been found to exhibit many therapeutic properties. This review covers the research and development carried out on biguanides and accounts the various therapeutic applications of drugs containing biguanide group-such as antimalarial, antidiabetic, antiviral, anticancer, antibacterial, antifungal, anti-tubercular, antifilarial, anti-HIV, as well as other biological activities.
