and Y are as defined herein useful in the treatment of a variety of disorders, including those in which the modulation of CCR5 receptors is implicated. Disorders that may be treated or prevented by the present derivatives include HIV and genetically related retroviral infections (and the resulting acquired immune deficiency syndrome, AIDS), rheumatoid arthritis, solid organ transplant reject (graft vs. host disease), asthma and COPR.

the size of R(2) affected both the regioselectivity and stereoselectivity of the displacement. Larger R(2) groups gave higher regio- and stereoselectivities: with R(2) = 3-pentyl, >98% S(N)2' regioselectivity and >98% anti stereoselectivity were observed. Bn(2)CuCNLi(2) gave stereoselectivities comparable to those observed with n-Bu(2)CuCNLi(2) but t-Bu(2)CuCNLi(2) exhibited much lower diastereofacial
Synthesis of <scp>Anti‐Pancreatic</scp> Cancer Natural Product Majusculamide D and Analogues Reveals a Preliminary <scp>Structure‐Activity</scp> Relationships
The total synthesis of majusculamide D (1) was achieved from commercially available materials. In addition, we synthesized eight analogues including three stereoisomers of majusculamide D that differ in the fatty acid chain. Six analogues including a simplified analogue 29 exhibited significant nanomolar-level IC50 values against Panc-1 cells in MTT assays. A preliminary SAR analysis indicated that
majusculamide D ( 1 )的全合成是由市售材料实现的。此外,我们还合成了八种类似物,包括三种脂肪酸链不同的 majusculamide D 立体异构体。在 MTT 测定中,包括简化类似物29在内的六种类似物对 Panc-1 细胞表现出显着的纳摩尔水平 IC 50值。初步的SAR分析表明majusculamide D的C 10 和C 2− C 3 不饱和双键上的羟基对于维持对Panc-1细胞的高活性以及C 40-Me 和C 42-Me基团的定向至关重要是可以忍受的。
