Preparation and characterization of multimodal hybrid organic and inorganic nanocrystals of camptothecin and gold

open access: yesActa Pharmaceutica Sinica B, 2019
We demonstrate a novel inorganic-organic crystalline nanoconstruct, where gold atoms were imbedded in the crystal lattices as defects of camptothecin nanocrystals, suggesting its potential use as simultaneous agents for cancer therapy and bioimaging. The

\u3csup\u3e99m\u3c/sup\u3eTc-Labeled C2A Domain of Synaptotagmin I as a Target-Specific Molecular Probe for Noninvasive Imaging of Acute Myocardial Infarction [PDF]

open access: yes, 2006
: The exposure of phosphatidylserine (PtdS) is a common molecular marker for both apoptosis and necrosis and enables the simultaneous detection of these distinct modes of cell death. Our aim was to develop a radiotracer based on the PtdS-binding activity

Selbstassemblierte (Aza‐)BODIPY Farbstoffe für Biomedizinische In Vivo Bildgebung

open access: yesAngewandte Chemie, EarlyView.
Dieses Minireview klassifiziert (Aza‐)BODIPY‐Farbstoffe anhand ihrer molekularen Stapelungsmodi und Aggregattypen (H‐, oblique‐ oder J‐Typ) in wässrigen Medien und setzt diese Merkmale in Beziehung zu ihrer multimodalen Bildgebungsleistung. Durch die Verknüpfung von molekularem Design, Exzitonenkopplung und pfadabhängiger Assemblierung stellen wir ...

Research progress in structural modification of Camptothecins

open access: yes生物医学转化
Camptothecin and its derivatives are alkaloids with broad-spectrum anti-tumor activities and have significant inhibitory effect on malignant tumors. Its derivatives such as irinotecan and topotecan have been on market over 20 years.

Relevance of the variability of the feline immunodeficiency virus in regard to pathogenicity and vaccination in New Zealand : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Animal Science, Massey University, Manawatū, New Zealand [PDF]

open access: yes, 2018
Cats infected with the feline immunodeficiency virus (FIV) show a range of clinical signs. Given the variability of the FIV genome, it is possible that there is variation in certain biological characteristics of FIV, such as pathogenicity.

Transplantable melanomas in hamsters and gerbils as models for human melanoma : sensitization in melanoma radiotherapy : from animal models to clinical trials [PDF]

open access: yes, 2018
The focus of the present review is to investigate the role of melanin in the radioprotection of melanoma and attempts to sensitize tumors to radiation by inhibiting melanogenesis. Early studies showed radical scavenging, oxygen consumption and adsorption

Self‐Assembled (Aza)BODIPY Dyes for Biomedical in Vivo Imaging

open access: yesAngewandte Chemie International Edition, EarlyView.
This minireview classifies (aza)BODIPY dyes according to their molecular stacking modes and aggregate types (H‐, oblique‐, or J‐type) in aqueous media, correlating these features with their multimodal imaging performance. By linking molecular design, exciton coupling, and pathway‐dependent assembly, we provide a framework for engineering next ...

Camptothecin and khat (Catha edulis Forsk.) induced distinct cell death phenotypes involving modulation of c-FLIPL, Mcl-1, procaspase-8 and mitochondrial function in acute myeloid leukemia cell lines

open access: yesMolecular Cancer, 2009
Background An organic extract of the recreational herb khat (Catha edulis Forsk.) triggers cell death in various leukemia cell lines in vitro. The chemotherapeutics camptothecin, a plant alkaloid topoisomerase I inhibitor, was tested side-by-side with ...

Linezolid prevents fibroblast activation and ameliorates tissue fibrosis by inhibition of mitochondrial translation

open access: yesArthritis &Rheumatology, Accepted Article.
Background Beyond its role as a ribosome‐targeting antibiotic, linezolid was recently shown to modulate immune responses by inhibiting mitochondrial translation. Since mitochondrial dysfunction is implicated in various fibrotic diseases, including systemic sclerosis (SSc), this study aimed to evaluate the antifibrotic potential of linezolid and ...

Are plants with anti-cancer activity resistant to crown gall? : A test of hypothesis [PDF]

open access: yes, 2007
The Crown gall tumour assay (CGTA) is one of several bench top bioassays recommended for the rapid screening of plants with anti-cancer activity. The rationale for the use of the bioassay is that the tumorogenic mechanism initiated in plant tissues by ...
