全球十大基因工程药物
没有知识产权,没有比竞争对手在具体技术领域长期的工作积累,要开发出年销售额10亿美元的新药是很难想象的。机会面前人人平等,如果能积极利用人类基因组的成果并结合我国遗传病的特点,再有10多亿人口的潜在用药市场,我们总有一天能入全球排行榜前列。

十大生物技术上市公司
依照不同的比较体系,十大生物 技术上市企业的排名是不同的.本文的比较标准是企业1999年的收入.若依照公司市值排名,一些基因组公司的名次会上升,这和投资者的吹捧炒作关系密切。

生物技术业内巨子
生物技术产业之父-Robert Swanson
生物技术界的比尔.盖茨- Rathmann
善于制造资本神话的金融奇才-Mark Levin
最大的生物技术公司
Genentech公司发展简史


生物技术产业之父-Robert Swanson
Robert Swanson是生物技术走出实验室和跨入商界的见证人。流传下来的故事是这样的:1976年,谋职于Kleiner Perkins 公司的时年29岁的风险投资家Swanson耳闻革命性的发现---重组DNA技术,他敏锐地捕捉到了这项基因工程关键技术的商业机会。年轻人拜访了技术发明人之一Boyer,一番热情鼓动,无疑使科学家更明确了基因剪接技术的商业价值;于是就有了后来的Genentech的诞生,Swanson出任公司CEO,两年后(1978年),人类历史上第一个采用重组DNA技术的基因工程产品胰岛素得以成功生产。

生物技术界的比尔.盖茨- Rathmann
Rathmann作为Amgen的第一任首席执行官直至1990年退休,十年风雨为世界贡献了两个年销售十亿美元的基因工程药物,诞生了世界上最大的生物技术企业.回眸生物技术和信息技术近二十年的发展历程,会发现许多惊人的相似点,两个行业的领路人都是集群众智慧之大成者,善于团结高智商的技术人员为团队开发目标而奋斗,都有老道的营销经验,把对技术的洞察力转化为转化为商业运作的核心竞争力.最重要的是他们都成功了,乃至Microsoft和Amgen同时列入Nasdaq在香港的五种交易股票。相比软件产业,基因工程产业把产品推向市场的周期更长,资金投入强度更大,这种挑战对应了Rathmann的融资能力,生物技术的烧钱能力使其现金流量难以熬过六个月,而Rathmann在保持融资的同时,从未采取上当铺的手法,让Amgen度过了漫长的创业期.如今,Rathmann又到Icos公司二次创业,大概是英雄相惜,Gates也在其中投入了数千万美元.

善于制造资本神话的金融奇才-Mark Levin
Millennium Pharmaceuticals公司1996年公开上市,在Nasdaq市场一直火爆。上市时交易价为12美元,而今已跃至150多美元(2000-9-02),发行量300多万股,市值近5亿美元。该公司的业绩因其从事基因组方面工作而拥有大量的功能基因专利,备受生物技术投资者追捧。更离不开Levin与大制药公司的结盟。目前估计给大公司结盟迎来20亿美元的进帐,令同行更为嫉妒的是这种签字活动同时维护了企业的权益。

最大的生物技术公司
安进(Amgen)公司是全球最大的独立生物技术公司,诚如其英文名取意应用分子生物学,该公司一直致力于蛋白类基因工程药物的生产. Amgen公司的发展是及其迅捷的, 其市值目前约700亿美元,排名世界500强之200多位,1992首次排入财富500强.Amgen目前上市的三个药物为EPOGEN (Epoetin alfa), NEUPOGEN (Filgrastim) 和INFERGEN (Interferon alfacon-1). Epogen是Amgen公司的第一个产品,1999年的销售额约18亿美元(Neupogen约12亿美元),该药的利润原动力是1987年10月批准的基于DNA序列的专利权(),对知识产权的保护其实是目前资源配置的最佳方式,是赢得国家竞争力的根本保证。类似的例子还有微软,在此不做赘述.1999年Amgen的研发费用为823百万美元. 公司1980年由几个科学家和风险投资家创立,1981年运作后得到了1900万美元风险资金的支持,CEO为Rathmann. 1983,1986,1987年先后在NASDQ发行股票.

生物技术股富翁TOP 100排行榜(2000年度)

据<<基因工程新闻>>报道,截止2000年3月1日,排名前100名的持生物技术股的富翁股票面值72.3亿美元,1999年的该统计为14.1亿美元,1998年为17.6亿美元,1997年为19.6亿美元,1996年为20.5亿美元.
首富仍为 William K. Bowes,其持有股票组合为 Amgen, XOMA和 Lynx,面值约68.6亿美元. 有意思的是,这100名持股人也存在高学历逐年上升的趋势.拥有博士学位的富翁从95年到2000年依次为64,63,72,69,89,96。这种文凭现象可引发对股市多层面的思索。

Oncogene
A gene thought to be capable of producing cancer.
Oncology
Study of tumors.
Phenotype
The observable characteristics of an organism as opposed to the set of genes it possesses (its genotype).The phenotype that an organism manifests is a result of both genetic and environmental factors. Therefore, organisms with the same genotype may display different phenotypes due to environmental factors. Conversely, organisms with the same phenotypes may have different genotypes.

A complex biological molecule composed of a chain of units called amino acids. Proteins have many different functions: structure(collagen); movement (actin and myosin); catalysis (enzymes); transport (hemoglobin); regulation of cellular processes (insulin); and response to the stimuli (receptor proteins on surface of all cells).The information for making proteins is stored in the sequence of nucleotides in the DNA molecule.
Protein engineering
A technique used in the production of proteins with new or artificial amino acid sequences.

Tissue culture
A procedure for growing or cloning enough cells through in vitro techniques to make a tissue.
T lymphocytes (T cells)
White blood cells, produced in the bone marrow, that aid B cells in making antibodies to fight bacterial infections. They also are instrumental in rejection of foreign tissue, and may be important in the body’s defense against cancer.

A change in the genetic structure of an organism as a result of the uptake and incorporation of foreign DNA.
Transposon
A mobile genetic element that can move from one location in the gene and reinsert at another site.
