Mogroside VI B，一种葫芦糖苷，从罗汉果粗提物中分离得到。Mogroside VI B 对 PGC-1α转录有激活作用。

PKM2 inhibitor G是丙酮酸激酶抑制剂。

L-6355 is an agent of bioactive chemicals.

PDE11-IN-1 是一种PDE11抑制剂，可用于肾上腺机能不全的研究。

4-Nitrophenyl phenylphosphonate is a substrate for 5'-nucleotide phosphodiesterases. It is a more preferable substrate to 5'-nucleotide phosphodiesterases than naturally occurring nucleotides or bis(4-nitrophenyl) phosphate because of its stability, ease of synthesis, and higher rate of hydrolysis under saturating conditions.

Alkannin 是一种有效且特异性的肿瘤型丙酮酸激酶-M2 (PKM2) 抑制剂，不抑制 PKM1 和丙酮酸激酶-L (PKL)。Alkannin 是一种潜在的抗癌剂。

PKM2-IN-1 (compound 3k) 是丙酮酸激酶 M2 (PKM2) 抑制剂，其IC50=2.95 μM。
