Fluoridated organofluoroborates comprising at least one .sup.18F atom and precursors thereto, for use in PET scanning.

The present disclosure provides dihydrazone compounds having high affinity to Aβ protein and Tau protein and derivatives thereof. The structure of the compounds is shown by formula (I)

##STR00001##

Provided herein are certain compounds and imaging agents useful for detecting a disease or condition associated with protein aggregation, compositions thereof, and methods of their use.

Provided are imaging agents comprising a compound of Formula I, or a pharmaceutically acceptable salt thereof, and methods of their use.

##STR00001##

Provided are imaging agents comprising a compound of Formula I, or a pharmaceutically acceptable salt thereof, and methods of their use.

##STR00001##

The present invention relates to radiolabeled LPA1 receptor antagonists of Formula (I) or pharmaceutically acceptable salts thereof, wherein all the variables are as defined herein, which are useful for the quantitative imaging of LPA1 receptors in mammals.

##STR00001##

The invention relates to a marking precursor incorporating a chelator or fluorination group for radiolabelling with 44Sc, 47Sc, 55Co, 62Cu, 64Cu, 67Cu, 66Ga, 67Ga, 68Ga, 89Zr, 86Y, 90Y, 90Nb, 99mTc, 111ln, 135Sm, 140Pr, 159Gd, 149Tb, 160Tb, 161Tb, 165Er, 166Dy, 166Ho, 175Yb, 177Lu, 186Re, 188Re, 213Bi and 225Ac or with 18F, 131I or 211At, and one or two biological targeting vectors which are coupled to the chelator or fluorinating group via one or more squaric acid groups.

The invention relates to water soluble .sup.18F-prosthetic groups and the synthesis and use of .sup.18F-labeled biological molecules containing the .sup.18F-prosthetic groups for imaging various processes within the body, for detecting the location of molecules associated with disease pathology, and for monitoring disease progression are disclosed.

Conjugates of an active agent attached to a targeting moiety, such as at least one HSP90 binding moiety, via a linker, have been designed. Such conjugates can provide improved temporospatial delivery of the active agent, improved biodistribution and penetration in tumor, and/or decreased toxicity. Methods of making the conjugates and the formulations thereof are provided. Methods of administering the formulations to a subject in need thereof are provided, for example, to treat or prevent cancer.

The present technology provides compounds as well as compositions including such compounds useful in targeted radiotherapy of cancer and/or mammalian tissue overexpressing prostate specific membrane antigen (“PSMA”) where the compounds are represented by the following:

##STR00001## or a pharmaceutically acceptable salt thereof,

##STR00002## or a pharmaceutically acceptable salt thereof,

##STR00003## or a pharmaceutically acceptable salt thereof,
wherein M.sup.1 is independently at each occurrence an alpha-emitting radionuclide. Equivalents of such compounds are also disclosed.
