New colorimetric cytotoxicity assay for anticancer-drug screening.
TLDR
The SRB assay provides a sensitive measure of drug-induced cytotoxicity, is useful in quantitating clonogenicity, and is well suited to high-volume, automated drug screening. Expand
Evaluation of a soluble tetrazolium/formazan assay for cell growth and drug sensitivity in culture using human and other tumor cell lines.
TLDR
The new XTT reagent provides for a simplified, in vitro cell growth assay with possible applicability to a variety of problems in cellular pharmacology and biology, but still shares many of the limitations and potential pitfalls of MTT or other tetrazolium-based assays. Expand
Feasibility of drug screening with panels of human tumor cell lines using a microculture tetrazolium assay.
TLDR
Since the microculture tetrazolium assay provides sensitive and reproducible indices of growth as well as drug sensitivity in individual cell lines over the course of multiple passages and several months' cultivation, it appears suitable for initial-stage in vitro drug screening. Expand
Isolation and Characterization of Griffithsin, a Novel HIV-inactivating Protein, from the Red Alga Griffithsia sp.*
TLDR
Data suggest that GRFT is a new type of lectin that binds to various viral glycoproteins in a monosaccharide-dependent manner and could be a potential candidate microbicide to prevent the sexual transmission of HIV and AIDS. Expand
Discovery of cyanovirin-N, a novel human immunodeficiency virus-inactivating protein that binds viral surface envelope glycoprotein gp120: potential applications to microbicide development
TLDR
The novel 11-kDa virucidal protein, named cyanovirin-N (CV-N), is isolated and sequenced from cultures of the cyanobacterium (blue-green alga) Nostoc ellipsosporum and is highly resistant to physicochemical denaturation, further enhancing its potential as an anti-HIV microbicide. Expand
Some practical considerations and applications of the national cancer institute in vitro anticancer drug discovery screen
TLDR
Practical considerations and selected specific examples are selected, particularly illustrating research applications of the NCI screen that may be more broadly applicable to the search for new anticancer drug development leads with novel profiles of antitumor activity and/or mechanisms of action. Expand
Display and analysis of patterns of differential activity of drugs against human tumor cell lines: development of mean graph and COMPARE algorithm.
TLDR
This study developed a key methodological tool, the mean graph, which allowed the transformation of the numerical cell line response data into graphic patterns that were particularly expressive of differential cell growth inhibition. Expand
Tetrazolium-based assays for cellular viability: a critical examination of selected parameters affecting formazan production.
TLDR
Results indicate that MTT specific activity is significantly influenced by a number of parameters and suggest that assay conditions should be established which minimize their effects. Expand
The guttiferones, HIV-inhibitory benzophenones from Symphonia globulifera, Garcinia livingstonei, Garcinia ovalifolia and Clusia rosea
Abstract Extracts from species of the tropical plant genera Symphonia , Garcinia and Clusia (Guttiferae) have yielded a series of new polyisoprenylated benzophenone derivatives named guttiferones A–EExpand
New soluble-formazan assay for HIV-1 cytopathic effects: application to high-flux screening of synthetic and natural products for AIDS-antiviral activity.
TLDR
This simple microassay minimizes the number of plate manipulations typically required with other assay methods and, coupled with computerized data collection and analysis, facilitates large-scale screening of agents for potential antiviral activity. Expand
