The present disclosure is directed dye compounds containing a hydrazinyl substituent and optionally, one or more negatively charged groups, such as sulfonate, phosphate, phosphonate, and/or carboxylate groups and dye compounds containing an aminooxy substitutent. The compounds are useful in the detection of analytes containing aldehyde and ketone groups, including, for example, glycans.

Small molecule calpain modulator compositions and pharmaceutical compositions can be prepared and used as therapeutic agents. Exemplary compositions include non-macrocyclic a-keto amide derivatives. The therarapeutic agents can be used for treating fibrotic disease or a resulting secondary disease state or condition. The small molecules can competitively bind with calpastatin and/or inhibit calpain through contact with CAPN1, CAPN2, and/or CAPN9 enzymes.
