You will be shown an abstract from a biomedical research paper. Given this abstract, your task is to extract all unique entities of the following types: ["Protein", "Chemical"].

Please return the output as a JSON object of the format: {"Chemical" : ["Dexamethasone", ...], "Protein" : ["BRCA-1", ...]}. The keys should be entity types and values should be lists of extracted entities belonging to the corresponding type. If you cannot find entities belonging to a specific type, the value should be [].

Only output the JSON object and do not include any additional text.

Abstract:

Glycosylation enhances the anti-migratory activities of isomalyngamide A analogs.
Three, new, fully synthetic glycosylated isomalyngamide A analogs 4-6 were prepared and evaluated for their anti-migratory activities in human breast cancer cells. The results of the study show that two glycosylated derivatives 4 and 5, containing mannose and galactose appendages, suppress metastatic events (e.g., migration, invasion and adhesion) in human breast adenocarcinoma MDA-MB-231 cells at "nontoxic" concentration levels. In contrast, derivative 6 that contains a lactose moiety, displays a less potent activity. The findings show that monosaccharide rather than disaccharide appendages to the isomalyngamide A backbone more greatly influence cell migration and invasive ability. Evidence has been gained for a mechanism for inhibition of metastatic activities in MDA-MB-231 cells by 4 and 5, involving inactivation of the expression of p-FAK and paxillin through the integrin-mediated antimetastatic pathway.
