What is the real name of CPH4

Is CPH4 from the science fiction movie 'Lucy' real?

Devashish That

ATTENTION: I believe this is a promotional statement from the director that is not actually based. The drug may not be known until he specifies it.

What to watch out for

  • The sixth week is the time when the brain begins to form. In other words, the cell ball began to form brain and heart-like organs. The cerebral cortex is formed and the synapses begin to connect.

  • If such a chemical actually exists, which one will it be? It could be a substrate that binds some enzyme that helps develop the brain, or it could be the enzyme itself (in both cases, the enzyme is important)

  • Now the real problem, there are tons of enzymes that bind 100 times more substrates. Which is the one?

My guess: Why not the one with that highest production and activity?

It is a female steroid hormone in the estrogen family. Not only does it affect gender in the embryo, it also helps with neural development and neuroprotection. Estradiol and the Developing Brain, by MARGARET M. McCARTHY, American Physiological Society, 2008

The paper Low-Dose Estradiol, published in 2005, changes brain activity. suggest that the low dose of this drug may actually alter brain activity in adults.

The paper, published in the Journal of Neuroscience, Estrogen, Menopause, and the Aging Brain, How Basic Neuroscience Can Affect Hormone Therapy in Women, supports the theory that it can affect intellectual age.

PS: It is neither the only option nor the right connection. But it is one of the many possibilities.

Other possibilities:

  • Fructose-1,6-bisphosphatase substrates can actually affect brain activity.
  • FMRP (fragile X protein for intellectual disability) substrates


  1. The basics of brain development

  2. Fructose-1,6-bisphosphatase in the human fetal brain and liver during development


I would expect something more pregnancy specific.

Strange thinking ♦

Welcome to skeptics. If any of these answers actually had an effect approaching the claim, I would accept them as plausible answers, but you haven't shown that.

@Devashish What I think you need to do is focus on the evidence relevant to the real question. For example, show that there are significant chemicals that affect the fetus's brain, but also study why and how they can affect the adult brain and, perhaps most importantly, why we haven't noticed the effect before, when they are frequent (such as estradiol).

@ DevashishDas way better. However, I would extent take greater account of the potential candidates' impact on adults.


1) Estradiol is not a protein but a steroid hormone. 2) Estradiol is far from the only pregnancy-related substance that affects brain development. What about cortisol, prolactin, oxytocin, placental lactogen, vasopressin, progesterone etc etc etc?
