Qualitative aspects of the degradation of mitomycins in alkaline solution.

Journal of pharmaceutical and biomedical analysis

Beijnen JH, den Hartigh J, Underberg WJ.
PMID: 16867711
J Pharm Biomed Anal. 1985;3(1):71-9. doi: 10.1016/0731-7085(85)80008-x.

The major degradation product in alkaline solution of mitomycin A, mitomycin C and porfiromycin is the corresponding 7-hydroxymitosane. The isolation and the physico-chemical and analytical properties of these compounds and their derivatized analogues are discussed. Data are presented on...

Palladium-catalyzed cascade cyclizations involving C-C and C-X bond formation: strategic applications in natural product synthesis.

Chemical Society reviews

Holman KR, Stanko AM, Reisman SE.
PMID: 34037626
Chem Soc Rev. 2021 Jul 21;50(14):7891-7908. doi: 10.1039/d0cs01385d. Epub 2021 May 26.

Palladium-catalyzed cascade cyclizations (PCCs) are powerful synthetic tools that enable rapid assembly of polycyclic scaffolds. Palladium complexes can promote a variety of carbon-carbon and carbon-heteroatom bond-forming reactions with high chemo-, enantio-, and diastereoselectivity. The combination of multiple ring-forming elementary...

A Novel Class of CC-1065 and Duocarmycin Analogues Subject to Mitomycin-Related Reductive Activation.

The Journal of organic chemistry

Boger DL, Garbaccio RM.
PMID: 11674758
J Org Chem. 1999 Oct 29;64(22):8350-8362. doi: 10.1021/jo991301y.

A new class of DNA alkylating agents is described that incorporate the quinone of the mitomycins, which is thought to impart tumor cell selectivity as a result of preferential reduction and activation in hypoxic tumors, into the AT-selective binding...

Enantioselective Synthesis of (+)-Mitomycin K by a Palladium-Catalyzed Oxidative Tandem Cyclization.

Angewandte Chemie (International ed. in English)

Gu QS, Yang D.
PMID: 28425184
Angew Chem Int Ed Engl. 2017 May 15;56(21):5886-5889. doi: 10.1002/anie.201701895. Epub 2017 Apr 20.

The mitomycins, a family of bioactive natural products, feature a compact 6/5/5-fused polycyclic ring structure densely decorated with highly reactive and/or fragile quinone, amino ketal, and aziridine as well as carbamate moieties. It is this striking feature that has...

Quinone-Based Drugs: An Important Class of Molecules in Medicinal Chemistry.

BACKGROUND: Several quinones are on the pharmaceutical market as drugs for the treatment of several diseases.OBJECTIVE: The aim of this review was to provide an overview of the quinones that have become drugs for several therapeutic applications.METHODS: We have...

Mitomycins syntheses: a recent update.

Beilstein journal of organic chemistry

Andrez JC.
PMID: 19777135
Beilstein J Org Chem. 2009 Jul 08;5:33. doi: 10.3762/bjoc.5.33.

Mitomycins are a class of very potent antibacterial and anti-cancer compounds having a broad activity against a range of tumours. They have been used in clinics since the 1960's, and the challenges represented by their total synthesis have challenged...

Synthetic Studies Towards the Mitomycins: Construction of the Tetracyclic Core via a Reductive Aminocyclization Reaction.

Tetrahedron letters

Gubler DA, Williams RM.
PMID: 20161278
Tetrahedron Lett. 2009 Jul 22;50(29):4265-4267. doi: 10.1016/j.tetlet.2009.05.004.

The tetracyclic core of the mitomycin family of natural products has been formed in one step from an acyclic precursor via a reductive aminocyclization reaction. Additionally, the 8-membered benzazocine can be prepared without the need for prior activation of...

The aminoshikimic acid pathway in bacteria as source of precursors for the synthesis of antibacterial and antiviral compounds.

Journal of industrial microbiology & biotechnology

Escalante A, Mendoza-Flores R, Gosset G, Bolívar F.
PMID: 34374768
J Ind Microbiol Biotechnol. 2021 Aug 10; doi: 10.1093/jimb/kuab053. Epub 2021 Aug 10.

The aminoshikimic (ASA) pathway comprises a series of reactions resulting in the synthesis of 3-amino-5-hydroxybenzoic acid (AHBA), present in bacteria such as Amycolaptosis mediterranei and Streptomyces. AHBA is the precursor for synthesizing the mC7N units, the characteristic structural component...
