19F MRI is valuable for in vivo imaging due to the only trace amounts of fluorine in biological systems. Because of the low sensitivity of MRI however, designing new fluorochemicals remains a significant challenge for achieving sufficient 19F signal. Here, we describe a new class of high-signal, water-soluble fluorochemicals as 19F MRI imaging agents. A polyamide backbone is used for tuning the proteolytic stability to avoid retention within the body, which is a limitation of current state-of-the-art perfluorochemicals. We show that unstructured peptides containing alternating N-?-trifluoroacetyllysine and lysine provide a degenerate 19F NMR signal. 19F MRI phantom images provide sufficient contrast at micromolar concentrations, showing promise for eventual clinical applications. Finally, the degenerate high signal characteristics were retained when conjugated to a large protein, indicating potential for in vivo targeting applications, including molecular imaging and cell tracking.

The anti-apoptotic protein survivin is highly expressed in cancer cells but has a very low expression in fully differentiated adult cells. Overexpression of survivin is positively correlated with cancer cell resistance to chemotherapy and radiotherapy, cancer cell metastasis, and poor patient prognosis. Therefore, selective targeting survivin represents an attractive strategy for the development of anticancer therapeutics. Herein, we reported the extensive structural modification of our recently discovered selective survivin inhibitor UC-112 and the synthesis of thirty-three new analogs. The structure-activity relationship (SAR) study indicated that replacement of the benzyloxy moeity in UC-112 with an indole moiety was preferred to other moieties. Among these UC-112 analogs, 10f, 10h, 10k, 10n showed the most potent antiproliferative activities. Interestingly, they were more potent against the P-glycoprotein overexpressing cancer cell lines compared with the parental cancer cell lines. Mechanistic studies confirmed that new analogs maintained their unique selectivity against survivin among the IAP family members. In vivo study using 10f in a human A375 melanoma xenograft model revealed that it effectively inhibited melanoma tumor growth without observable acute toxicity. Collectively, this study strongly supports the further preclinical development of selective survivin inhibitors based on the UC-112 scaffold.

Abstract Indolyl-3-carbonylnitriles are compounds with demonstrated utility as intermediates in organic chemistry. However, their synthesis remains a challenge, requiring the use of toxic sources of cyanide, and often proceeding in low yields. Accordingly, presented here is a new synthesis of these versatile reactants, via dehydration of easily accessible alpha-oxoacetamides in generally high yields under simple reaction conditions.
