The Chimera Seed by Matthew Tully.
Here is the book cover synopsis:
Immortality is possible, but the cost of eternal life is death. Richard Tiernan's sudden death sparks a chain of events that threatens the survival of the human species. The visionary scientist's son and only heir, Dr. Michael Tiernan, inherits Oisín Pharmaceuticals and learns of his father's astonishing secret. Hidden away in the little Sardinian town of Boroneddu, Michael discovers his father's greatest legacy: the fountain of youth.
In possession of Dionysinol, the most dynamic anti-aging drug ever engineered, Michael Tiernan aspires to turn Oisín Pharmaceuticals into an empire. His plans rapidly unravel when he becomes ensnared in a cutthroat game of pharmaceutical espionage and learns just how far some people will go to acquire immortality and how far others will go to destroy it.
The Chimera Seed transports the reader to Italy, where the genetically-engineered Niamh grape grows, and back to the United States, where politics, corruption, greed, obsession, revenge, passion and moral imperatives make Dionysinol the most sought-after and dangerous substance on Earth.
