Our product line of cyclic oligoadenylates has been expanded by two new products:
These compounds are fluorinated versions of the bacterial second messengers c-tetraAMP (Cat. No. C 335) and c-triAMP (Cat. No. C 362), respectively, which are expected to have increased metabolic stability.
The extensive measures taken at Biolog in March 2020 to protect against the spread of COVID-19 enable us now to ensure smooth continuation of all processes despite the renewed lockdown in Germany. We are still available for you, all incoming inquiries and orders will still be processed quickly and reliably, as usual.
Please contact us with any questions or concerns.
8-[Alexa Fluor® 488]-AHA-cAMP is a fluorescently labelled analogue of cAMP, and 8-Azido-cGMP can be used for photoaffinity labelling of cGMP binding proteins.
We have expanded our product lines of cyclic dinucleotides and cyclic oligonucleotides by three new products:
The cyclic oligonucleotide 2',2'',2''',2'''',2''''',2''''''-Hexa-F-c-hexadAMP (cFA6, Cat. No. H 038) is a fluorinated version of the bacterial second messenger c-hexaAMP (Cat. No.: C 332) with increased metabolic stability.

Biolog is one of the sponsors of the "Nanodomains in cyclic nucleotide signalling: from mechanisms to therapeutic approaches" meeting which will be held at the Imperial College London, UK, September 16-18, 2019.
This meeting gathers renowned experts who will highlight recent advances in understanding the molecular mechanisms underlying cAMP signalling in nano-scale compartments and how such local signalling regulates key cellular and physiological processes in the cardiovascular system. A further focus will be the relevance of cAMP signalling compartments as pharmacological targets for the treatment of cardiovascular diseases. Cutting-edge methodology such as the use of various high-resolution imaging techniques and advanced biosensors, animal models, and the current state of drug development, will be discussed.
For further information please follow the link to the meeting's website.

We have added four new polymer-linked dimeric (PLD) cGMP analogues to our product portfolio which contain two cGMP moieties linked by polymer chains of different lengths:
These membrane-permeant cGMP dimers exhibit enhanced PKG activation properties by addressing two binding sites simultaneously with a single molecule.
8-(3-Butynylthio)guanosine-3',5'-cyclic monophosphate (8-Bu(3-yne)T-cGMP, Cat. No. B 185) can be used for copper-catalyzed azide-alkyne cycloaddition (CuAAC) "click chemistry" reactions with azide-containing molecules.

We have added eight novel cyclic dinucleotides to our continuously expanding product line:
We have added isotope labelled [13C20,15N10]-c-diGMP (Cat. No. C 183) to our continuously expanding product line of cyclic dinucleotides.
[13C20,15N10]-c-diGMP is useful as an internal standard for the detection and quantification of the bacterial signalling nucleotide c-diGMP in bacterial extract samples by LC-MS/MS analysis.
For further information on the [13C20,15N10]-c-diGMP please view the corresponding product detail page.
BIOLOG sponsors the upcoming annual Conference 2019 of the Association for General and Applied Microbiology (VAAM 2019) which will take place in Mainz, Germany, March 17-20, 2019, and the bi-annual FASEB Science Research Conference on NAD+ Metabolism and Signaling to be held in Dublin, Ireland, June 23-28, 2019.
We are pleased to announce a significant price reduction for our product Rp,Rp-2'3'-c-diAMPSS (syn. c[A(2',5')pS[Rp]-A(3',5')pS[Rp]], Cat. No. C 224). Please follow the link to the product detail page for further information.
Rp,Rp-2'3'-c-diAMPSS is a synthetic cyclic dinucleotide with improved stability against degradation by phosphodiesterases and enhanced binding affinity to STING. The related structure c[A(2',5')pS[Sp]-A(3',5')pS[Rp]], Cat. No. C 223 is also available.
Cyclic oligoadenylates such as c-tetraAMP were found to be novel bacterial second messengers involved in the Type III CRISPR-Cas-associated detection and degradation of invasive genetic elements in many prokaryotes.

"Future Products" list structures which are nearly ready for commercialisation. The list will be permanently updated and contains already > 80 items at the moment.
pppG(2',5')pA is considered to be the linear catalytic intermediate in the enzymatic production of 2',3' - cGAMP (aka c[G(2',5')pA(3',5')p], BIOLOG Cat. No. C 161) by the mammalian innate immune DNA sensor cGAMP synthase (cGAS). According to Hall e t al. (2017) human stimulator of interferon genes STING 155 - 341 does not bind pppG(2',5')pA at concentrations of up to 50 μM.
In pppApG a 5'-ATP unit is connected with a 5'-GMP unit via a 3' → 5' linkage to form a linear dinucleotide. pppApG is a potential endogenous metabolite of the metazoan second messenger 2',3'-cGAMP (c[G(2',5')pA(3',5')p], Cat. No. C 161) and/or of the bacterial signalling nucleotide 3'3'-cGAMP (c-(ApGp), Cat. No. C 117). Kranzusch et al. (2014) reported pppApG to be the linear dinucleotide intermediate in the enzymatic production of 3',3'-cGAMP by the Vibrio cholerae pathogenicity factor DncV. References: Kranzusch, P.J. et al., Cell, 158, 1011 - 1021 (2014); Deng, T. et al., J. Virol., 80, 2337 - 2348 (2006).
With Rp-2'-F-dATP-α-S (Cat. No. D 220) and Sp-2'-F-dATP-a-S (Cat. No. D 219) the sulfur-modified analogues of 2'-deoxy-2'-fluoro-ATP (Cat. No. D 074), which are considered to be metabolically more stable, have been added to our product list. In addition, c[3'-[sCya7]-AHC-G(2',5')pA(3',5')p], (Cat. No. C 240), a new NIR fluorescent 2',3'-cGAMP analogue has joined the cyclic dinucleotide tools set.
8-Br-2',3'-cAMP (Cat. No. B 280) is now available from Biolog. This compound is considered to be a membane-permeable analogue of 2',3'-cAMP (Cat. No. A 307) and was recently used by Kosmacz et al. (2018) to study the role of 2',3'-cAMP in the formation of stress granules in Arabidopsis thaliana (Reference: Kosmacz et al., Plant Physiol., 177, 411 - 421 (2018): "Interaction of 2',3'-cAMP with Rbp47b Plays a Role in Stress Granule Formation").
Biolog now offers the endogenous Transient Receptor Potential Melastatin 2 (TRPM2) channel superagonist and potential novel second messenger 2'-deoxy-ADPR (Reference: Fliegert et al., Nat. Chem. Biol., 13, 1036 - 1044 (2017): "2'-Deoxyadenosine 5'-diphosphoribose is an Endogenous TRPM2 Superagonist").
We have added three new products to our product line of NAD and ADPR analogues:
Our product DEACM-caged cAMP (Cat. No. D 042) which was temporarily out of stock, is available again. DEACM-caged cAMP is a caged precursor of the second messenger cAMP and releases both cAMP and a fluorescent coumarin analogue upon irradiation.
Biolog is pleased to be one of the sponsors of the upcoming 70th Annual Meeting of the German Society for Hygiene and Microbiology e. V. (DGHM, February 19-21, 2018, Bochum, Germany, www.dghm-kongress.de) and of the 3rd German Pharm-Tox Summit (DGPT, February 26-March 1, 2018, Göttingen, Germany, www.gpts-kongress.de).

The newly discovered bacterial second messenger c-hexaAMP (syn.: cyclic hexaadenylate / c-A6 / cA6) is now available from Biolog.
c-hexaAMP was recently reported by Niewoehner et al. (2017) and Kazlauskiene et al. (2017) to be a signalling molecule in prokaryotes, involved in the Type III CRISPR-Cas-associated detection and degradation of invasive genetic elements.
We have added a number of new NAD+ analogues, mostly modified at the 8-position of the adenine ring, to our product catalogue. Many of these structures are described in a collaborative paper recently published in Science: Gibson et al., Science, 353, 45 - 50 (2016): "Chemical Genetic Discovery of PARP Targets Reveals a Role for PARP-1 in Transcription Elongation".
