1. Biosynthesis of 2'-Chloropentostatin and 2'-Amino-2'-Deoxyadenosine Highlights a Single Gene Cluster Responsible for Two Independent Pathways in Actinomadura sp. Strain ATCC 39365
Yaojie Gao, Gudan Xu, Pan Wu, Jin Liu, You-Sheng Cai, Zixin Deng, Wenqing Chen Appl Environ Microbiol. 2017 May 1;83(10):e00078-17. doi: 10.1128/AEM.00078-17. Print 2017 May 15.
2'-Chloropentostatin (2'-Cl PTN, 2'-chloro-2'-deoxycoformycin) and 2'-amino-2'-deoxyadenosine (2'-amino dA) are two adenosine-derived nucleoside antibiotics coproduced by Actinomadura sp. strain ATCC 39365. 2'-Cl PTN is a potent adenosine deaminase (ADA) inhibitor featuring an intriguing 1,3-diazepine ring, as well as a chlorination at C-2' of ribose, and 2'-amino dA is an adenosine analog showing bioactivity against RNA-type virus infection. However, the biosynthetic logic of them has remained poorly understood. Here, we report the identification of a single gene cluster (ada) essential for the biosynthesis of 2'-Cl PTN and 2'-amino dA. Further systematic genetic investigations suggest that 2'-Cl PTN and 2'-amino dA are biosynthesized by independent pathways. Moreover, we provide evidence that a predicted cation/H+ antiporter, AdaE, is involved in the chlorination step during 2'-Cl PTN biosynthesis. Notably, we demonstrate that 2'-amino dA biosynthesis is initiated by a Nudix hydrolase, AdaJ, catalyzing the hydrolysis of ATP. Finally, we reveal that the host ADA (designated ADA1), capable of converting adenosine/2'-amino dA to inosine/2'-amino dI, is not very sensitive to the powerful ADA inhibitor pentostatin. These findings provide a basis for the further rational pathway engineering of 2'-Cl PTN and 2'-amino dA production.IMPORTANCE 2'-Cl PTN/PTN and 2'-amino dA have captivated the great interests of scientists, owing to their unusual chemical structures and remarkable bioactivities. However, the precise logic for their biosynthesis has been elusive for decades. Actually, the identification and elucidation of their biosynthetic pathways not only enrich the biochemical repertoire of novel enzymatic reactions but may also lay solid foundations for the pathway engineering and combinatorial biosynthesis of this family of purine nucleoside antibiotics to generate novel hybrid analogs with improved features.
2. Ring-expanded ("Fat") nucleosides as broad-spectrum anticancer and antiviral agents
Ramachandra S Hosmane Curr Top Med Chem. 2002 Oct;2(10):1093-109. doi: 10.2174/1568026023393147.
Ring-expanded (ldauo;fat") nucleosides (RENs) described in this review are analogues of purine nucleosides containing a 5:7-fused imidazodiazepine or imidazotriazepine ring system. They are both of natural and synthetic origin, and are of chemical, biochemical, biophysical, as well as medicinal interest. The important natural RENs include coformycin, pentostatin, azepinomycin, adechlorin, and adecypenol. A majority of them are synergistic antitumor and/or antiviral antibiotics which potentiate the effects of other antitumor or antiviral compounds through inhibition of key enzymes such as adenosine deaminase or guanase which would otherwise metabolically degrade the active compounds into therapeutically less potent or totally inactive counterparts. However, despite the fact that some of the natural RENs such as coformycins are the strongest known enzyme inhibitors, they have not been proven as effective clinically as anticipated because of the extremely high toxicity associated with their use. Nevertheless, pentostatin (2'-deoxycoformycin) is a conspicuous exception as it is gaining wide attention in recent years as a clinically effective therapeutic agent against leukemias and lymphomas. Many of the recently reported synthetic RENs, by contrast, possess biological activities of their own, in particular against a wide spectrum of cancers and viruses with little toxicity to the host cells, and thus hold considerable promise as chemotherapeutic agents. The promising preliminary in vitro data concerning the effects of RENs on human cancers, in particular prostate and breast cancer cells, support their further pursuit in animal and clinical studies. RENs also carry promise against many viral infections belonging to the families of hepatitis, herpes, and respiratory infections, most notable being the hepatitis B (HBV), hepatitis C (HCV), and the West Nile (WNV) viruses.
3. An Fe2+ - and α-Ketoglutarate-Dependent Halogenase Acts on Nucleotide Substrates
Chunhua Zhao, Shan Yan, Qin Li, Hucheng Zhu, Zhiyu Zhong, Ying Ye, Zixin Deng, Yonghui Zhang Angew Chem Int Ed Engl. 2020 Jun 8;59(24):9478-9484. doi: 10.1002/anie.201914994. Epub 2020 Apr 1.
While halogenated nucleosides are used as common anticancer and antiviral drugs, naturally occurring halogenated nucleosides are rare. Adechlorin (ade) is a 2'-chloro nucleoside natural product first identified from Actinomadura sp. ATCC 39365. However, the installation of chlorine in the ade biosynthetic pathway remains elusive. Reported herein is a Fe2+ -α-ketoglutarate halogenase AdeV that can install a chlorine atom at the C2' position of 2'-deoxyadenosine monophosphate to afford 2'-chloro-2'-deoxyadenosine monophosphate. Furthermore, 2',3'-dideoxyadenosine-5'-monophosphate and 2'-deoxyinosine-5'-monophosphate can also be converted, albeit 20-fold and 2-fold, respectively, less efficiently relative to the conversion of 2'-deoxyadenosine monophosphate. AdeV represents the first example of a Fe2+ -α-ketoglutarate-dependent halogenase that converts nucleotides into chlorinated analogues.
