On July 31, 2021, Panagopoulos, Anastasios; Balalas, Thomas; Mitrakas, Achilleas; Vrazas, Vassilios; Katsani, Katerina R.; Koumbis, Alexandros E.; Koukourakis, Michael I.; Litinas, Konstantinos E.; Fylaktakidou, Konstantina C. published an article.Product Details of 89-77-0 The title of the article was The 6-Nitro-Quinazolin-4(3H)-one Exhibits Photodynamic Effects and Photodegrades Human Melanoma Cell Lines. A Study on the Photoreactivity of Simple Quinazolin-4(3H)-ones. And the article contained the following:
Photochemo and photodynamic therapies are minimally invasive approaches for the treatment of cancers and powerful weapons for competing bacterial resistance to antibiotics. Synthetic and naturally occurring quinazolinones are considered privileged anticancer and antibacterial agents, with several of them to have emerged as com. available drugs. In the present study, applying a single-step green microwave irradiation mediated protocol we have synthesized eleven quinazolinon-4(3H)-ones, from cheap readily available anthranilic acids, in very good yields and purity. These products were irradiated in the presence of pBR322 plasmid DNA under UVB, UVA and visible light. Four of the compounds proved to be very effective DNA photocleavers, at low concentrations, being time and concentration dependent as well as pH independent. Participation of reactive oxygen species was related to the substitution of quinazolinone derivatives 6-Nitro-quinazolinone in combination with UVA irradiation was found to be in vitro photodestructive for three cell lines; glioblastoma (U87MG and T98G) and mainly melanoma (A-375). Thus, certain appropriately substituted quinazolinones may serve as new lead photosensitizers for the development of promising biotechnol. applications and as novel photochemo and photodynamic therapeutics. The experimental process involved the reaction of 2-Amino-4-chlorobenzoic acid(cas: 89-77-0).Product Details of 89-77-0
