Compounds of Formula I are useful inhibitors of CDK 4, CDK6, and FLT3. Such compounds are useful in treating cancer and various other disease conditions. Compounds of Formula I have the following structure: 2. The method of claim 1 , wherein Ris a C-Ccycloalkyl group that is unsubstituted or is substituted with 1-3 substituents independently selected from unsubstituted —(C-Calkyl) claim 1 , —OH claim 1 , halo claim 1 , —O—(C-Calkyl) claim 1 , —COH claim 1 , —C(═O)—O—(C-Calkyl) claim 1 , —C(═O)—NR′R″ claim 1 , —NR′R″ claim 1 , or a substituted —(C-Calkyl) claim 1 , wherein the substituted —(C-Calkyl) is substituted with 1-3 substituents independently selected from halo claim 1 , —OH claim 1 , —OCH claim 1 , —S(═O)—CH claim 1 , or —C(═O)—CH.3. The method of claim 2 , wherein Ris a cyclohexyl group substituted with a —(C-Calkyl) group.5. The method of claim 1 , wherein Ris a group of Formula IA or IB.6. The method of claim 5 , wherein Ris a group of Formula IA.7. The method of claim 1 , wherein:{'sup': '2', 'sub': 5', '7', '1', '6, 'Ris a C-Ccycloalkyl group that is unsubstituted or is substituted with 1-3-(C-Calkyl) groups;'}{'sup': '3a', 'sub': 1', '3', '1', '3, 'Ris selected from —H, —(C-Calkyl), or —O—(C-Calkyl);'}{'sup': '3b', 'Ris —H;'}{'sup': '3c', 'Ris —H;'}{'sup': '4', 'Ris —H;'}{'sup': '5', 'Ris —H;'}{'sup': '6', 'sub': 1', '6', '1', '6', '1', '6', '1', '6', '2', '1', '6', '1', '6, 'Ris selected from —(C-Calkyl), —C(═O)—(C-Calkyl), or —C(═O)—C(═O)—OH, wherein the alkyl group of the —(C-Calkyl) and —C(═O)—(C-Calkyl) groups is unsubstituted or is substituted with 1-3 substituents independently selected from —OH, F, —S(═O)—(C-Calkyl), or —O—(C-Calkyl);'}{'sup': '7a', 'Ris —H;'}{'sup': 7b', '1, 'Ris —H; or is absent if Ris a group of Formula IB or Formula ID;'}{'sup': 7c', '1, 'Ris —H; or is absent if Ris a group of Formula IA or Formula IC;'}{'sup': '8a', 'Ris —H;'}{'sup': '8b', 'Ris —H;'}{'sup': '8c', 'sub': 1', '6, 'Ris selected from —H, —OH, or unsubstituted ...
