Initial SAR exploration identified the 4‑fluoro‑anilide substitution as critical for affinity (IC₅₀ = 45 nM). Further introduction of a pyridin‑3‑yl moiety at the C‑2 position increased potency 3‑fold, resulting in (IC₅₀ = 12 nM for p110α) (Figure 1A). Kinome profiling revealed >250‑fold selectivity against p110β (IC₅₀ = 3.1 µM) and >500‑fold versus the remaining 338 kinases (Figure 1B).

The crew lived in a tightly knit community. Weekly “cultural nights” featured cuisine and music from the many nations represented onboard, and a rotating “Storytime” where senior crew members recounted tales of early spaceflight—both to preserve history and to remind everyone why they were venturing into the unknown.

And Elara, now known as the Ambassador of the Nexus, continued her work, ensuring that the gateway remained a bridge to new possibilities, rather than a barrier to the unknown.

At T‑00:03:00, Captain Kwon addressed the crew via the ship’s omnipresent holo‑array:
