1. A method for treating a cancer selected from the group consisting of skin, prostate, colorectal, pancreas, kidney, ovary, mammary, liver, tongue, smooth muscle tissue,
leukemia, lymphoma, non-Hodgkin lymphoma, myeloma, and multiple myeloma comprising administering to a mammal having or predisposed to said cancer a therapeutically effective amount of a compound of Formula (I) ##STR00682## or a pharmaceutically
acceptable salt, stereoisomeric or tautomeric form thereof, wherein: R.sup.1 is C.sub.1-C.sub.8 alkyl, C.sub.2-C.sub.8 alkenyl, C.sub.2-C.sub.8 alkynyl, or C.sub.3-C.sub.7 cycloalkyl; R.sup.2 is H; Q is --B(OH).sub.2, --B(OR.sup.14).sub.2, or a cyclic
boronic ester wherein said cyclic boronic ester contains from 2 to 20 carbon atoms, and, optionally, a heteroatom which can be N, S, or O; R.sup.14 is H, C.sub.1-C.sub.4 alkyl, cycloalkyl, cycloalkylalkyl, aryl, or aralkyl; X is R.sup.AC(.dbd.O)--;
R.sup.ANHC(.dbd.O)--, R.sup.AS(O).sub.2--, R.sup.ASC(.dbd.O)--, or R.sup.A; R.sup.A is C.sub.1-C.sub.20 alkyl optionally substituted with R.sup.20; C.sub.2-C.sub.20 alkenyl optionally substituted with R.sup.20; C.sub.2-C.sub.20 alkynyl optionally
substituted with R.sup.20; carbocyclyl optionally substituted with 1-5 R.sup.22; or heterocarbocyclyl optionally substituted with 1-5 R.sup.22; R.sup.20 is selected from the group consisting of: --OR.sup.20a, --SR.sup.20a--S(.dbd.O)R.sup.20a,
--S(.dbd.O).sub.2R.sup.20a, --S(.dbd.O).sub.2NHR.sup.20a, --SC(.dbd.O)R.sup.20a, --C(.dbd.O)R.sup.20a, --C(.dbd.O)NHR.sup.20a, --C(.dbd.O)O--R.sup.20a, phthalimido, --(O-alkyl), --O-alkyl-OH, --(O-alkyl).sub.r-OH, --OR.sup.20c, --SR.sup.20c,
--O--alkyl-R.sup.20c, --S(.dbd.O).sub.2--R.sup.20c, --S(.dbd.O).sub.2--NHR.sup.20c, --SC(.dbd.O)R.sup.20c, --C(.dbd.O)R.sup.20c, --C(.dbd.O)OR.sup.20c, --C(.dbd.O)NHR.sup.20c, carbocyclyl optionally substituted with 1-5 R.sup.22; and heterocarbocyclyl
optionally substituted with 1-5 R.sup.22; R.sup.20a is C.sub.1-C.sub.20 alkyl, C.sub.2-C.sub.20 alkenyl, or C.sub.2-C.sub.20 alkynyl; wherein said alkyl, alkenyl, or alkynyl is optionally substituted by one or more halo, C.sub.1-C.sub.4 alkyl, aryl,
heteroaryl or --NHR.sup.20b; R.sup.20c is carbocyclyl optionally substituted with 1-5 R.sup.22; or heterocarbocyclyl optionally substituted with 1-5 R.sup.22; R.sup.22 is selected from the group consisting of: C.sub.1-C.sub.10 alkyl, C.sub.2-C.sub.10
alkenyl, C.sub.2-C.sub.10 alkynyl, phenyl, halo, haloalkyl, alkoxy, thialkoxy, amino, alkylamino, dialkylamino, carboxyl, alkyl-OC(.dbd.O)--, alkyl-C(.dbd.O)--, aryl-OC(.dbd.O)--, alkyl-OC(.dbd.O)NH--, aryl-OC(.dbd.O)NH--, alkyl-C(.dbd.O)NH--,
alkyl-C(.dbd.O)O--, (alkyl-O).sub.r-alkyl, HO-(alkyl-O).sub.r-alkyl-, --OH, --SH, --CN, --N.sub.3, --CNO, --CNS, alkyl-S(.dbd.O)--, alkyl-S(.dbd.O).sub.2--, H.sub.2NS(.dbd.O)--, and H.sub.2NS(.dbd.O).sub.2--; and r is 2, 3, 4, 5, 6, 7, 8, 9, or 10.
2. The method of claim 1, wherein X is R.sup.AC(.dbd.O)--. 3.
