One-Pot C–N/C–C Cross-Coupling of Methyliminodiacetic Acid Boronyl Arenes Enabled by Protective Enolization
Iterative cross-coupling is a highly efficient and versatile strategy for modular construction in organic synthesis, though this has historically been demonstrated solely in the context of C–C bond formation. A C–N cross-coupling of haloarene methyliminodiacetic acid (MIDA) boronates with a wide range of aromatic and aliphatic amines is reported. Successful cross-coupling of aliphatic amines was realized only through protective enolization of the MIDA group. This reaction paradigm was subsequently utilized to achieve a one-pot C–N/C–C cross-coupling sequence
Potent, Selective, and Orally Bioavailable Inhibitors of VPS34 Provide Chemical Tools to Modulate Autophagy <i>in Vivo</i>
Autophagy
is a dynamic process that regulates lysosomal-dependent
degradation of cellular components. Until recently the study of autophagy
has been hampered by the lack of reliable pharmacological tools, but
selective inhibitors are now available to modulate the PI 3-kinase
VPS34, which is required for autophagy. Here we describe the discovery
of potent and selective VPS34 inhibitors, their pharmacokinetic (PK)
properties, and ability to inhibit autophagy in cellular and mouse
models
Identification of Small Molecule Inhibitors and Ligand Directed Degraders of Calcium/Calmodulin Dependent Protein Kinase Kinase 1 and 2 (CaMKK1/2)
CaMKK2 signals through AMPK-dependent and AMPK-independent
pathways
to trigger cellular outputs including proliferation, differentiation,
and migration, resulting in changes to metabolism, bone mass accrual,
neuronal function, hematopoiesis, and immunity. CAMKK2 is upregulated
in tumors including hepatocellular carcinoma, prostate, breast, and
gastric cancer, and genetic deletion in myeloid cells results in increased
antitumor immunity in several syngeneic models. Validation of the
biological roles of CaMKK2 has relied on genetic deletion or small
molecule inhibitors with activity against several biological targets.
We sought to generate selective inhibitors and degraders to understand
the biological impact of inhibiting catalytic activity and scaffolding
and the potential therapeutic benefits of targeting CaMKK2. We report
herein selective, ligand-efficient inhibitors and ligand-directed
degraders of CaMKK2 that were used to probe immune and tumor intrinsic
biology. These molecules provide two distinct strategies for ablating
CaMKK2 signaling in vitro and in vivo

Discovery of an Acrylic Acid Based TetrahydroÂisoquinoline as an Orally Bioavailable Selective Estrogen Receptor Degrader for ERα+ Breast Cancer
Tetrahydroisoquinoline <b>40</b> has been identified as a potent ERα antagonist and
selective estrogen receptor degrader (SERD), exhibiting good oral
bioavailability, antitumor efficacy, and SERD activity in vivo. We
outline the discovery and
chemical optimization of the THIQ scaffold leading to THIQ <b>40</b> and showcase the racemization of the scaffold, pharmacokinetic studies
in preclinical species, and the in vivo efficacy of THIQ <b>40</b> in a MCF-7 human breast cancer xenograft model

Discovery of LSZ102, a Potent, Orally Bioavailable Selective Estrogen Receptor Degrader (SERD) for the Treatment of Estrogen Receptor Positive Breast Cancer
In
breast cancer, estrogen receptor alpha (ERα) positive
cancer accounts for approximately 74% of all diagnoses, and in these
settings, it is a primary driver of cell proliferation. Treatment
of ERα positive breast cancer has long relied on endocrine therapies
such as selective estrogen receptor modulators, aromatase inhibitors,
and selective estrogen receptor degraders (SERDs). The steroid-based
anti-estrogen fulvestrant (<b>5</b>), the only approved SERD,
is effective in patients who have not previously been treated with
endocrine therapy as well as in patients who have progressed after
receiving other endocrine therapies. Its efficacy, however, may be
limited due to its poor physicochemical properties. We describe the
design and synthesis of a series of potent benzothiophene-containing
compounds that exhibit oral bioavailability and preclinical activity
as SERDs. This article culminates in the identification of LSZ102
(<b>10</b>), a compound in clinical development for the treatment
of ERα positive breast cancer
