Modified cyclodextrins as broad-spectrum antivirals

Daniel Ortiz Trujillo, Francesco Stellacci, Natalia Gasilova, Samuel Thomas Jones, Matej Janecek, Valeria Cagno, Matteo Gasbarri

Viral infections kill millions of people and new antivirals are needed. Nontoxic drugs that irreversibly inhibit viruses (virucidal) are postulated to be ideal. Unfortunately, all virucidal molecules described to date are cytotoxic. We recently developed n ...

Oral transfer of chemical cues, growth proteins and hormones in social insects

Laurent Keller, Oksana Riba Grognuz, Daniel Ortiz Trujillo, Laure Menin

Social insects frequently engage in oral fluid exchange trophallaxis between adults, and between adults and larvae. Although trophallaxis is widely considered a food-sharing mechanism, we hypothesized that endogenous components of this fluid might underlie ...

Histidine Targeting Heterobimetallic Ruthenium(II)-Gold(I) Complexes

Paul Joseph Dyson, Daniel Ortiz Trujillo, Lucinda Kate Batchelor

Inspired by the preferential, allosteric binding of RAPTA-T and auranofin to the nucleosome core particle, we describe the design and synthesis of a series of heterobimetallic ruthenium(II)-gold(I) complexes with varying spacer lengths ranging from four to ...

Maternal allocation of carotenoids increases tolerance to bacterial infection in brown trout

Daniel Ortiz Trujillo, Laure Menin

Life-history theory predicts that iteroparous females allocate their resources differently among different breeding seasons depending on their residual reproductive value. In iteroparous salmonids there is typically much variation in egg size, egg number, ...

New melphalan derivatives for the treatment of retinoblastoma in combination with thermotherapy

Paul Joseph Dyson, Aurélien Bornet, Daniel Ortiz Trujillo, Farzaneh Fadaei Tirani, Jan Romano de Gea

Of the different modalities used to treat retinoblastoma, a chemothermotherapeutic regimen combining carboplatin and thermotherapy (also termed focal therapy), and the application of melphalan as a monotherapy, are particularly successful. Some studies ind ...

Dysfunction of the circadian clock in the kidney tubule leads to enhanced kidney gluconeogenesis and exacerbated hyperglycemia in diabetes

Daniel Ortiz Trujillo, Laure Menin, Hikari Ananda Infinity Yoshihara

The circadian clock is a ubiquitous molecular time-keeping mechanism which synchronizes cellular, tissue, and systemic biological functions with 24-hour environmental cycles. Local circadian clocks drive cell type- and tissuespecific rhythms and their dysr ...
