Organic #molecules delivered from #extraterrestrial materials may have played a key role in supplying building blocks for #life on #Earth.

Now scientists report all five canonical #nucleobases—purines (#adenine and #guanine) and pyrimidines (#cytosine, #thymine and #uracil)—in samples returned from the C-type #asteroid (162173) #Ryugu.

Samples from Ryugu, #Bennu and #Orgueil, which have a similar mineralogy and elemental composition, show purine-to-pyrimidine ratios negatively correlating with #ammonia.

These observations indicate that the nucleobases in these samples may have formed via a shared pathway depending on the physicochemical environment of the respective parent bodies.

The detection of diverse nucleobases in asteroid and meteorite materials demonstrates their widespread presence throughout the Solar System and reinforces the hypothesis that carbonaceous asteroids contributed to the #prebiotic chemical inventory of early Earth.

Chemical Soups Around Cool Stars

This artist's conception shows a young, hypothetical planet around a cool star. A soupy mix of potentially life-forming chemicals can be seen pooling around the base of the jagged rocks.

Happy to share our just accepted #review on #multitarget approaches for the #synthesis of #purine and #pyrimidine derivatives. From the #prebiotic/#abiotic origin of life to new #green #chemistry strategies for #drugdiscovery.
