Uses

Used in Pharmaceutical Industry:
Methyl 4-chloro-7-methoxyquinoline-6-carboxylate is used as an antimicrobial agent for treating infections after burns. Its ability to inhibit the growth of bacteria and other microorganisms makes it a valuable component in wound care and burn treatment.
Used in Research and Development:
Methyl 4-chloro-7-methoxyquinoline-6-carboxylate is used as a reagent in the preparation of naphthamides, which are inhibitors of vascular endothelial growth factor (VEGF) receptor tyrosine kinase. These inhibitors play a crucial role in various biological processes, including angiogenesis, cell proliferation, and cell migration. By targeting the VEGF receptor, naphthamides can potentially be used in the development of therapeutic agents for various diseases, such as cancer and age-related macular degeneration.

Naphthamides as novel and potent vascular endothelial growth factor receptor tyrosine kinase inhibitors: Design, synthesis, and evaluation

A series of naphthyl-based compounds were synthesized as potential inhibitors of vascular endothelial growth factor (VEGF) receptors. Investigations of structure-activity relationships led to the identification of a series of naphthamides that are potent inhibitors of the VEGF receptor tyrosine kinase family. Numerous analogues demonstrated low nanomolar inhibition of VEGF-dependent human umbilical vein endothelial cell (HUVEC) proliferation, and of these several compounds possessed favorable pharmacokinetic (PK) profiles. In particular, compound 48 demonstrated significant antitumor efficacy against established HT29 human colon adenocarcinoma xenografts implanted in athymic mice. A full account of the preparation, structure-activity relationships, pharmacokinetic properties, and pharmacology of analogues within this series is presented.

Evaluation of a series of naphthamides as potent, orally active vascular endothelial growth factor receptor-2 tyrosine kinase inhibitors

We have previously shown N-arylnaphthamides can be potent inhibitors of vascular endothelial growth factor receptors (VEGFRs). N-Alkyl and N-unsubstituted naphthamides were prepared and found to yield nanomolar inhibitors of VEGFR-2 (KDR) with an improved selectivity profile against a panel of tyrosine and serine/threonine kinases. The inhibitory activity of this series was retained at the cellular level. Naphthamides 3, 20, and 22 exhibited good pharmacokinetics following oral dosing and showed potent inhibition of VEGF-induced angiogenesis in the rat corneal model. Once-daily oral administration of 22 for 14 days led to 85% inhibition of established HT29 colon cancer and Calu-6 lung cancer xenografts at doses of 10 and 20 mg/kg, respectively.
