BN-81,674 is a bioactive chemical.

Cortistatin-29 is a neuropeptide that is structurally similar to somatostatin-28. It is produced by cleavage of preprocortistatin to procortistatin, which is cleaved at dibasic amino acids to form cortistatin-29 and cortistatin-14 as well as other partial cleavage products. Cortistatin mRNA is expressed in the human brain and in interneurons of the rat hippocampus and cerebral cortex. Cortistatin-29 binds to somatostatin (SST) receptors with IC50 values of 2.8, 7.1, 0.2, 3, and 13.7 nM for SST1-5, respectively. Cortistatin-29 is found at similar levels as cortistatin-14 in mouse AtT20 cells but is secreted at a lower level. Cortistatin-29 corresponds to residues 85-112 of the rat peptide sequence.

Veldoreotide (DG3173) TFA，一种生长抑素类似物，能够结合并激活SSTR 2 4 5。其在腺瘤中抑制生长激素分泌的效果相较于Octreotide更为显著。此外，Veldoreotide亦展现出作为镇痛剂的潜力。

Veldoreotide, also known as Somatoprim, is a unique somatostatin receptor subtypes 2-, 4- and 5-selective analogue which effectively reduces GH secretion in human GH-secreting pituitary adenomas, even in Octreotide non-responsive tumours.

AZD4320 是一种BCL2 BCLxL 双重抑制剂，是 BH-3 类似物，对 KPUM-MS3、KPUM-UH1 和 STR-428 细胞，IC50 值分别为 26 nM、17 nM 和 170 nM。
