新华网巴黎９月７日专电（记者李学梅）法国国家科研中心等５家科研机构７日发表联合公报称，它们的研究人员日前成功研制出了一种新分子，能阻止艾滋病病毒侵入人体细胞。

公报称，迄今，科学家大约开发出２５种抗艾滋病病毒的分子，其中不少是通过阻止病毒复制来达到遏制病情发展的目的。使用这类分子可大大延长患者的寿命，但同时也带有副作用，并会引发病人的抗药性。

此次新开发的分子名为ＣＤ４－ＨＳ，由糖和肽合成，它能够有效地阻止艾滋病病毒侵入人体细胞，副作用不大。研究人员接下来将对这种分子进行动物实验，以检验其有效性和安全性。

    该研究成果已刊登在最新一期英国《自然·化学生物学》杂志上。

     PARIS, September 7 (Xinhuanet, LI Xue-mei) French national scientific research centers, five research institutes issued a joint communique on the 7th, said their research staff has successfully developed a new molecule that can prevent HIV invade human cells.

     The communiqué said that so far, scientists have developed about 25 kinds of anti-HIV molecules, many of them are of viral replication by blocking progression of the disease to achieve the purpose of containment. The use of such molecules can significantly prolong life, but also with the side-effects, and will lead to the patient's resistance.

     The newly developed molecule called CD4-HS, from the sugar and peptide synthesis, it can effectively prevent HIV invades the human body cells, side effects do not. The researchers next will be of such molecules in animals to test its effectiveness and safety.

     The research results have been published in the latest issue of the British "Nature Chemical Biology" magazine.
