  Positive allosteric modulators (PAMs) of nicotinic acetylcholine receptors (nAChR) are important therapeutic candidates as well as valuable research tools. We identified a novel type II PAM, (R)-7-bromo-N-(piperidin-3-yl)benzo[b]thiophene-2-carboxamide (Br-PBTC), which both increases activation and reactivates desensitized nAChRs. This compound increases acetylcholine-evoked responses of α2* and α4* nAChRs, but is without effect on α3* or α6* nAChRs ("*" indicates presence of other nAChR subunits). Br-BPTC binds to the C-terminal extracellular sequences of a4 subunits, which is also a PAM site for steroid hormone estrogens such as 17-β estradiol. Br-PBTC is much more potent than estrogens. Like 17-P-estradiol, the non-steroid Br-PBTC only requires one α4 subunit to potentiate nAChR function, and its potentiation is stronger with more a4 subunits. This feature enables Br-BPTC to potentiate activation of (α4β2)(α6β2)β3 but not (α6β2)2β3 nAChRs. Various bioactive analogs of Br-PBTC are provided.

  正向变构调节剂（PAMs）对尼古丁乙酰胆碱受体（nAChR）是重要的治疗候选药物，同时也是有价值的研究工具。我们发现了一种新型II型PAM，(R)-7-溴-N-(哌啶-3-基)苯并[b]噻吩-2-甲酰胺（Br-PBTC），它既增加了激活，又重新激活了脱敏的nAChRs。这种化合物增加了α2*和α4* nAChRs对乙酰胆碱的响应，但对α3*或α6* nAChRs没有影响（"*"表示存在其他nAChR亚基）。Br-BPTC结合到α4亚基的C端外胞外序列，这也是类固醇激素雌激素如17-β雌二醇的PAM位点。Br-PBTC比雌激素更有效。与17-β雌二醇一样，非类固醇Br-PBTC只需要一个α4亚基来增强nAChR功能，并且随着更多的α4亚基，其增强作用更强。这个特性使Br-BPTC能够增强(α4β2)(α6β2)β3而不是(α6β2)2β3 nAChRs的激活。提供了各种生物活性类似物的Br-PBTC。

  Myeloid cell leukemia 1 (Mcl-1), a member of the Bcl-2 family of proteins, is overexpressed and amplified in various cancers and promotes the aberrant survival of tumor cells that otherwise would undergo apoptosis. Here we describe the discovery of potent and selective Mcl-1 inhibitors using fragment-based methods and structure-based design. NMR-based screening of a large fragment library identified two chemically distinct hit series that bind to different sites on Mcl-1. Members of the two fragment classes were merged together to produce lead compounds that bind to Mcl-1 with a dissociation constant of <100 nM with selectivity for Mcl-1 over Bcl-xL and Bcl-2. Structures of merged compounds when complexed to Mcl-1 were obtained by X-ray crystallography and provide detailed information about the molecular recognition of small-molecule ligands binding Mcl-1. The compounds represent starting points for the discovery of clinically useful Mcl-1 inhibitors for the treatment of a wide variety of cancers.
