一般說明
从印度植物毛喉鞘蕊花中分离出的主要细胞渗透性二萜。在低剂量时，它用作正性肌力药。在较高剂量下，由于其作为平滑肌肉松弛药的作用，因此可作为低血压和血管舒张剂。在有效剂量下未观察到主要副作用。毛喉素的药理活性是由于其激活腺苷酸环化酶（EC50 = 4 µM），导致cAMP水平升高。毛喉素正性肌力效应的确切机制尚不清楚，但可能与cAMP依赖性Na+通透性增加有关，导致Ca2+释放间接增加。抑制大鼠肾系膜细胞中的MAP激酶（IC50 = 25 µM）。还充当Hh途径拮抗剂。显示抑制小脑颗粒细胞中的凋亡，并诱导静息人B淋巴细胞中的凋亡。
从印度植物毛喉鞘蕊花中分离出的具有心脏活性的二萜。在低剂量时，在狗、猫、自发性高血压和正常大鼠以及离体豚鼠心脏中用作正性肌力药。在较高剂量下，由于其作为平滑肌肉松弛药的作用，因此可作为低血压和血管舒张剂。在有效剂量下未观察到主要副作用。膜和完整细胞中腺苷酸环化酶（EC50 = 4 µM）的快速可逆激活剂。不影响鸟苷酸环化酶或环核苷酸磷酸二酯酶的活性。毛喉素′正性肌力效应的确切机制尚不清楚，但可能与cAMP依赖性Na+通透性增加有关，导致Ca2+释放间接增加。抑制大鼠肾系膜细胞中的MAP激酶（IC50 = 25 µM）。还充当Hh途径拮抗剂。显示抑制小脑颗粒细胞中的凋亡，并诱导静息人B淋巴细胞中的凋亡。
生化／生理作用
产物不与ATP竞争。
可逆：否
细胞可渗透性：是
靶标IC50：25 µM，抑制大鼠肾系膜细胞中的MAP激酶；腺苷酸环化酶激活的EC50 = 4 µM。
注意
据报道，乙醇抑制毛喉素介导的腺苷酸环化酶的活化。DMSO为推荐溶剂；在DMSO终浓度为≤5%时，几乎不会抑制腺苷酸环化酶的活化。
警告
毒性：有害（C）
重構
在复溶后存放于冰箱（4°C）。DMSO储备液可在4°C下稳定保存4个月。

cAMP production upon activation of Gs by G protein-coupled receptors has classically been considered to be plasma membrane-delimited, but a shift in this paradigm has occurred in recent years with the identification of several receptors that continue to signal from

Class B G protein-coupled receptors (GPCRs) are notoriously difficult to target by small molecules because their large orthosteric peptide-binding pocket embedded deep within the transmembrane domain limits the identification and development of nonpeptide small molecule ligands.

The Hippo pathway is a highly conserved signalling route involved in organ size regulation. The final effectors of this pathway are two transcriptional coactivators, yes-associated protein (YAP) and transcriptional coactivator with PDZ-binding motif (WWTR1 or TAZ). Previously, we showed aberrant

The parathyroid hormone (PTH) type 1 receptor (PTHR) is a class B G protein–coupled receptor (GPCR) that regulates mineral ion, vitamin D, and bone homeostasis. Activation of the PTHR by PTH induces both transient cell surface and sustained endosomal cAMP

Mammalian genomes comprise largely intergenic noncoding DNA with numerous cis-regulatory elements. Whether and how the size of intergenic DNA affects gene expression in a tissue-specific manner remain unknown. Here we show that genes with extended intergenic regions are preferentially expressed
