Trials explained

A peptide raised the share reaching a cell collection target to 92.5 percent

In 122 adults with a bone marrow cancer preparing for a transplant of their own stem cells, adding the peptide to the standard injection raised the share who collected enough cells in two sessions from 26.2 percent to 92.5 percent. A later comparison against the drug already in use found no advantage.

From the reference

Browse all 74 entries
5-Amino-1MQ

5-Amino-1MQ is not a peptide at all; it is built as a small chemical compound rather than a chain of linked amino acids, and it works by blocking an enzyme called NNMT that cells use during energy processing.

Epitalon

Epitalon is a four-amino-acid peptide copied from a substance the pineal gland, a small gland deep in the brain, makes on its own.

Adalank

Adalank comes from chemists altering Selank in the lab; Selank itself is a short manmade peptide built originally from tuftsin, a natural peptide involved in immune signalling.

Adamax

Adamax is a lab-built variant of Semax, a peptide studied in Russia for decades for its effects on memory and brain protection.

Adipotide

Adipotide is a lab-made compound built from two joined parts: one part latches onto the network of small blood vessels supplying white body fat, while the other part carries a signal that causes those vessel-lining cells to die off.

AHK-Cu

AHK-Cu is a copper complex made in the lab, joining three linked amino acids to a single copper ion; it sits close to a natural molecule called GHK-Cu, differing from it by only one building block.
